That means, when it is 12:00 AM UTC, it is 5:45 a.m.
Nepal is 15 minutes ahead of India's time zone. During Daylight Saving Time, the area switches to an offset of UTC - 2:30. For example: Newfoundland in Canada uses Newfoundland Standard Time (NST) which has an offset of UTC - 3:30. Some time zones may contain valid minutes offset. Note: The minutes of time zones are not necessarily 0. 09Z - As format Z This date time has no offset from UTC (or 0 hour offset). 09-0100 - As format # +-HHmm This date time has an offset of -1 hour from UTC. 09+07:00 - As format +-HH:mm This date time has an offset of seven hours from UTC. If a time part is included, an offset from UTC can also be included using any of these four formats: It is important in a world of browsers app, mobile app and serverless functions in the cloud, to understand time zones. Any of the Date Parts Can Have a Time PartĢ020-W06-5 09 - Example with week date part: Day 5 of Week 6 at 9 a.m.Ģ020-039 09 - Example with ordinal date part and hour time part: Day 39 of 2020 at 9 a.m. 09:30:26.123 - Example with hour, minute, second, and millisecond time part.Ģ0200208T080910,123 - Example with short date and time up to ms, separated by comma.Ģ0200208T080910.123 - Example with short date and time up to ms.Ģ0200208T080910 - Example with short date and time up to seconds.Ģ0200208T0809 - Example with short date and time up to minutes.Ģ0200208T08 - Example with short date and time, hours only. 09:30:26 - Example with hour, minute, and second time part.
09:30 - Example with hour and minute time part. 09 - Same example with hour time part separated by a space. T09 - Example with hour time part separated by a T. The time part is separated from the date part by either a space or an uppercase T. You can specify a short version of the above like this:Ģ020W065 - Example with short week, weekday specification.Ģ020039 - Example with short ordinal date. :)Ģ020-039 - This example has an ordinal date part: it says Day 39 of 2020. There are some unusual but quite useful formats, like:Ģ020-W06-5 - This example has a week date part: it says Week 6, Day 5 of 2020. In this example, we just have a calendar date part and no time part (02 is February).
#ISO DATE FORMAT ISO#
An ISO 8601 String Requires a Date Part but Time Part Is Optional Below you will find an explanation of the main ISO 8601 strings.
There are many variants by which a date time can be represented as ISO 8601. (in local time as there is no time zone offset specified-more on that below). ISO 8601 represents date and time by starting with the year, followed by the month, the day, the hour, the minutes, seconds and milliseconds.įor example, 15:00:00.000, represents the 10th of July 2020 at 3 p.m. Most confusing is the fact that some locales swap the position of the month, for example, can be interpreted as the eighth of April or the fourth of August. ISO 8601 Formatsĭate/time formats can be confusing because various locales of the world tend to represent date time differently. The intended audience is decision services integrators, and this is not for rules authors. In this blog, we will further our knowledge by going over the ISO 8601 format in some detail. These are important issues and concepts to understand particularly in a world of browsers app, mobile app and serverless functions in the cloud, We saw usages of UTC and we started talking about the ISO 8601 date/time format as one of the formats accepted in the JSON payload of decision services. In a previous blog- Dealing With Date and Time With Corticon.js-we discussed the issues around date and time in distributed systems.
