Perl 5 version 26.1 documentation
Converts a time as returned by the time function to a 9-element list with the time analyzed for the local time zone. Typically used as follows:
All list elements are numeric and come straight out of the C `struct tm'.
$hourare the seconds, minutes, and hours of the specified time.
$mdayis the day of the month and
$monthe month in the range
0..11, with 0 indicating January and 11 indicating December. This makes it easy to get a month name from a list:
$yearcontains the number of years since 1900. To get a 4-digit year write:
- $year += 1900;
To get the last two digits of the year (e.g., "01" in 2001) do:
- $year = sprintf("%02d", $year % 100);
$wdayis the day of the week, with 0 indicating Sunday and 3 indicating Wednesday.
$ydayis the day of the year, in the range
0..365in leap years.)
$isdstis true if the specified time occurs during Daylight Saving Time, false otherwise.
In scalar context, localtime returns the ctime(3) value:
The format of this scalar value is not locale-dependent but built into Perl. For GMT instead of local time use the gmtime builtin. See also the Time::Local module (for converting seconds, minutes, hours, and such back to the integer value returned by time), and the POSIX module's strftime and mktime functions.
To get somewhat similar but locale-dependent date strings, set up your locale environment variables appropriately (please see perllocale) and try for example:
%b, the short forms of the day of the week and the month of the year, may not necessarily be three characters wide.
For a comprehensive date and time representation look at the DateTime module on CPAN.
