They correspond to the C library routines C<strftime> and C<ctime>. =over 4 =item time2str(TEMPLATE, TIME [, ZONE]) C<time2str> converts C<TIME> into an ASCII string using the conversion specification given in C<TEMPLATE>. C<ZONE> if given specifies the zone which the output is required to be in, C<ZONE> defaults to your current zone. =item strftime(TEMPLATE, TIME [, ZONE]) C<strftime> is similar to C<time2str> with the exception that the time is passed as an array, such as the array returned by C<localtime>. =item ctime(TIME [, ZONE]) C<ctime> calls C<time2str> with the given arguments using the conversion specification C<"%a %b %e %T %Y\n"> =item asctime(TIME [, ZONE]) C<asctime> calls C<time2str> with the given arguments using the conversion specification C<"%a %b %e %T %Y\n"> =back =head1 MULTI-LANGUAGE SUPPORT Date::Format is capable of formating into several languages by creating a language specific object and calling methods, see L<Date::Language> my $lang = Date::Language->new('German'); $lang->time2str("%a %b %e %T %Y\n", time); I am open to suggestions on this. =head1 CONVERSION SPECIFICATION Each conversion specification is replaced by appropriate characters as described in the following list. The appropriate characters are determined by the LC_TIME category of the program's locale. %% PERCENT %a day of the week abbr %A day of the week %b month abbr %B month %c MM/DD/YY HH:MM:SS %C ctime format: Sat Nov 19 21:05:57 1994 %d numeric day of the month, with leading zeros (eg 01..31) %e like %d, but a leading zero is replaced by a space (eg 1..32) %D MM/DD/YY %G GPS week number (weeks since January 6, 1980) %h month abbr %H hour, 24 hour clock, leading 0's) %I hour, 12 hour clock, leading 0's) %j day of the year %k hour %l hour, 12 hour clock %L month number, starting with 1 %m month number, starting with 01 %M minute, leading 0's %n NEWLINE %o ornate day of month -- "1st", "2nd", "25th", etc. %p AM or PM %P am or pm (Yes %p and %P are backwards :) %q Quarter number, starting with 1 %r time format: 09:05:57 PM %R time format: 21:05 %s seconds since the Epoch, UCT %S seconds, leading 0's %t TAB %T time format: 21:05:57 %U week number, Sunday as first day of week %w day of the week, numerically, Sunday == 0 %W week number, Monday as first day of week %x date format: 11/19/94 %X time format: 21:05:57 %y year (2 digits) %Y year (4 digits) %Z timezone in ascii. eg: PST %z timezone in format -/+0000 C<%d>, C<%e>, C<%H>, C<%I>, C<%j>, C<%k>, C<%l>, C<%m>, C<%M>, C<%q>, C<%y> and C<%Y> can be output in Roman numerals by prefixing the letter with C<O>, e.g. C<%OY> will output the year as roman numerals. =head1 LIMITATION The functions in this module are limited to the time range that can be represented by the time_t data type, i.e. 1901-12-13 20:45:53 GMT to 2038-01-19 03:14:07 GMT. =head1 AUTHOR Graham Barr <gbarr@pobox.com> =head1 COPYRIGHT Copyright (c) 1995-2009 Graham Barr.
