In order to indicate that a time is measured in Universal Time (UTC), you can append a capital letter Z to a time as in 23:59:59Z or 2359z note: The z stands for the zero meridian, which goes through Greenwich in London, and. Universal Time (sometimes also called Zulu time) was called Greenwich mean Time (GMT) before 1972, however this term should no longer be used. Since the introduction of an international atomic time scale, almost all existing civil time zones are now related to utc, which is slightly different from the old and now unused gmt. The strings hh:mm, hhmm, or hh can be added to the time to indicate that the used local time zone is hh hours and mm minutes ahead of utc. For time zones west of the zero meridian, which are behind utc, the notation -hh:mm, -hhmm, or -hh is used instead. For example, central European Time (CET) is 0100 and.

A remark for readers from German speaking countries: The german standard din 5008, which specifies typographical rules for German texts written on typewriters, was updated in 1996-05.

Ss have been replaced by the iso notations hh:mm and hh:mm:ss. Those new notations are now also mentioned in the latest edition of the duden. The german alphanumeric date notation continues to be for example. August 1994. The corresponding Austrian standard has already used the iso 8601 date and time notations before.

The English 12h notation is more time difficult to understand. Please consider the 12h time to be a relic from the dark ages when Roman numerals were used, the number zero had not yet been invented and analog clocks were the only known form of displaying a time.

S., the paper military and computer programmers have been using the 24h notation for a long time. The old English 12h notation has many disadvantages like: It is longer than the normal 24h notation. It takes somewhat more time for humans to compare two times in 12h notation. It is not clear, how 00:00, 12:00 and 24:00 are represented. Even encyclopedias and style manuals contain contradicting descriptions and a common quick fix seems to be to avoid 12:00. Altogether and write noon, midnight, or 12:01. Instead, although the word midnight still does not distinguish between 00:00 and 24:00 (midnight at the start or end of a given day). It makes people often believe that the next day starts at the overflow from 12:59. M., which is a common problem not only when people try to program the timer of vcrs shortly after midnight.

A remark for readers from the. S.: The 24h time notation specified here has already been the de-facto standard all over the world in written language for decades. The only exception are a few English speaking countries, where still notations with hours between 1 and 12 and additions like. Are in wide use. The common 24h international standard notation is widely used now even in England (e.g. At airports, cinemas, bus/train timetables, etc.). Most other languages do not even have abbreviations like. And the 12h notation is certainly hardly ever used on Continental Europe to write or display a time. Even in the.

A single leap second 23:59:60 is inserted into the utc time summary scale every few years as announced by the International Earth Rotation Service in Paris, to keep utc from wandering away more than.9 s from the less constant astronomical time scale ut1, which is defined. In practice you are not very likely to see a clock showing 23:59:60. Most synchronized clocks resynchronize again to utc some time after a leap second has happened, or they temporarily slow down near the time of a leap seconds, to avoid any disruption that an out-of-range timestamp might otherwise cause. An example time is 23:59:59 which represents the time one second before midnight. As with the date notation, the separating colons can also be omitted as in 235959 and the precision can be reduced by omitting the seconds or both the seconds and minutes as in 23:59, 2359, or 23 It is also possible to add fractions.

This means that the following two notations refer to exactly the same point in time: 24:00 00:00 In case an unambiguous representation of time is required, 00:00 is usually the preferred notation for midnight and not 24:00. Digital clocks display 00:00 and not 24:00. Iso 8601 does not specify, whether its notations specify a point in time or a time period. This means for example that iso 8601 does not define whether 09:00 refers to the exact end of the ninth hour of the day or the period from 09:00 to 09:01 or anything else. The users of the standard must somehow agree on the exact interpretation of the time notation if this should be of any concern. If a date and a time are displayed on the same line, then always write the date in front of the time. If a date and a time value are stored together in a single data field, then iso 8601 suggests that they should be separated by a latin capital letter t, as in 19951231T235959.

For example, the 53 weeks of the worst case year 1976 started with 1976-W01-1 and ended with 1976-W53-7. On the other hand, considering the lowest number of the last week of a year, the worst case is a non-leap year like 1999 that starts with a friday, which ensures that the first three days of the year belong to the last week. In this case, the sunday of week 52 would be day number 352*7367,. Only the last days of the W52 reach into the next year and consequently, even a worst case year like 1999 has a week w52 including the days. Both day and year are useful units of structuring time, because the position of the sun on the sky, which influences our lives, is described by them. However the 12 months of a year are of some obscure mystic origin and have no real purpose today except that people are used to having them (they do not even describe the current position of the moon).

In some applications, a date notation is preferred that uses only the year and the day of the year between 001 and 365 (366 in leap years). The standard notation for this variant representing the day (that is day 035 of the year 1995) is or 1995035 leap years are years with an additional day yyyy-02-29, where the year number is a multiple of four with the following exception: If a year. For example, 1900 was not a leap year, but 2000 is one. Time of day the international standard notation for the time of day is hh:mm:ss where hh is the number of complete hours that have passed since midnight (00-24 mm is the number of complete minutes that have passed since the start of the hour (00-59. If the hour value is 24, then the minute and second values must be zero. Note: The value 60 for ss might sometimes be needed during an inserted leap second in an atomic time scale like coordinated Universal Time (UTC).

An abbreviated version of the year and week number like 1995W05 thesis is sometimes useful as a compact code printed on a product that indicates when it has been manufactured. Note: The iso standard avoids explicitly stating the possible range of week numbers, but this can easily be deduced from the definition. Possible iso week numbers are in the range 01. A year always has a week. (There is one historic exception: the year in which the Gregorian calendar was introduced had less than 365 days and less than 52 weeks.) Proof: Per definition, the first week of a year is W01 and consequently days before week w01 belong to the previous. Considering the highest possible week number, the worst case is a leap year like 1976 that starts with a thursday, because this keeps the highest possible number of days of W01 in the previous year,. In this case, the sunday of W52 of the worst case year is day number and days of W53 belong still to this year, which guarantees that in the worst case year day 4 (Thursday) of W53 is not yet in the next year,.

especially in Europe, it is often required to refer to a week help of a year. Week 01 of a year is per definition the first week that has the Thursday in this year, which is equivalent to the week that contains the fourth day of January. In other words, the first week of a new year is the week that has the majority of its days in the new year. Week 01 might also contain days from the previous year and the week before week 01 of a year is the last week (52 or 53) of the previous year even if it contains days from the new year. A week starts with Monday (day 1) and ends with Sunday (day 7). For example, the first week of the year 1997 lasts from to and can be written in standard notation as 1997-W01 or 1997W01 The week notation can also be extended by a number indicating the day of the week. For example, the day, which is the tuesday (day 2) of the first week of 1997, can also be written as 1997-W01-2 or 1997W012 for applications like industrial planning where many things like shift rotations are organized per week and knowing the week number and.

Iso 8601 is only specifying numeric notations and does not cover dates and times where words are used in the representation. It is not intended as a replacement for language-dependent worded date notations such. Dezember 2001 (German) or February 4, 1995 (us english). Iso 8601 should however be used to replace notations such as 2/4/95 and.30. Apart from the recommended primary standard notation yyyy-mm-dd, iso 8601 also specifies a number of alternative formats for use in applications with special requirements. All of these alternatives can easily and automatically be distinguished from each other: The hyphens can be omitted if compactness of the representation is more important than human readability, for example as in If only the month or even only the year is of interest.

For example, the fourth day of February in the year 1995 is written in the standard notation as, other commonly used notations are. 2/4/95, 4/2/95, 95/2/4,.2.1995, 04-feb-1995, 4-February-1995, and many more.

The date notation 2/4/5 has at least six reasonable interpretations (assuming that only the twentieth and twenty-first century are reasonable candidates in our life time). Advantages of the iso 8601 standard date notation compared to other commonly used variants: easily readable and writeable by software (no jan, feb. Table necessary) easily comparable and sortable with a trivial string comparison language independent can not be confused with other popular date notations consistency with the common 24h time notation system, where the larger units (hours) are also written in front of the smaller ones (minutes.
