| + | If this format specifier is present, trailing data in the string will not cause an error, but a warning instead | Use DateTime::getLastErrors() to find out whether trailing data was present. |
Unrecognized characters in the format string will cause the parsing to fail and an error message is appended to the returned structure. You can query error messages with DateTime::getLastErrors().
If format does not contain the character
! then portions of the generated time which are not
specified in format will be set to the current
system time.
If format contains the
character !, then portions of the generated
time not provided in format, as well as
values to the left-hand side of the !, will
be set to corresponding values from the Unix epoch.
The Unix epoch is 1970-01-01 00:00:00 UTC.
timeString representing the time.
timezoneA DateTimeZone object representing the desired time zone.
If timezone is omitted and
time contains no timezone,
the current timezone will be used.
Bilginize:
The
timezoneparameter and the current timezone are ignored when thetimeparameter either contains a UNIX timestamp (e.g. 946684800) or specifies a timezone (e.g. 2010-01-28T15:00:00+02:00).
