ISO 8601 is the international standard for the representation of dates and times.
Example (Complete date)
It can be written without specifying the day (YYYY-MM):
Example (Year and month)
It can be written without month and day (YYYY):
Example (Only year)
It can be written with added hours, minutes, and seconds (YYYY-MM-DDTHH:MM:SS):
Example (Complete date plus hours, minutes, and seconds)
The T in the date string, between the date and time, indicates UTC time.
|UTC (Universal Time Coordinated) is the same as GMT (Greenwich Mean Time).|
Long dates are most often written with a "MMM DD YYYY" syntax like this:
Month and day can be in any order:
And, month can be written in full (January), or abbreviated (Jan):
Commas are ignored. Names are case insensitive:
Short dates are most often written with an "MM/DD/YYYY" syntax like this:
|Month is written before day in all short date and ISO date formats.|

When getting a date, without specifying the time zone, the result is converted to the browser's time zone.
In other words: If a date/time is created in GMT (Greenwich Mean Time), the date/time will be converted to CDT (Central US Daylight Time) if a user browses from central US.
