T Timezone abbreviation, if known; otherwise the GMT offset. Examples: EST , MDT , +05
Z Timezone offset in seconds. The offset for timezones west of UTC is always negative, and for those east of UTC is always positive. -43200 through 50400

c ISO 8601 date 2004-02-12T15:19:21+00:00

Unrecognized characters in the format string will be printed as-is. The Z format will always return 0 when using gmdate() .

Note:

Since this function only accepts int timestamps the u format character is only useful when using the date_format() function with user based timestamps created with date_create() .

Return Values

Returns the formatted date string on success.
