注意:

The "W" in the "ISO year with ISO week" and "ISO year with ISO week and day" formats is case-sensitive, you can only use the upper case "W".

The "T" in the SOAP, XMRPC and WDDX formats is case-sensitive, you can only use the upper case "T".

The "Unix Timestamp" format sets the timezone to UTC.

up down 2 Bilge at steam250 dot com ¶1 year ago Unix timestamps also accept a microseconds specifier. e.g. @1607974647.503686 is valid and will be parsed as 2020-12-14 19:37:27.503686+00. up down -3 tuxedobob ¶6 years ago When trying to create a DateTime from a string, PHP essentially doesn't care about leading zeroes in hours.

When converting a DateTime to a string, PHP will honor leading zeroes as documented in date(). add a note
