perl -ne 'use POSIX; /^([0-9]+)-([0-9]+)-([0-9]+)-([0-9]{2})([0-9]{2})(.*)/; print mktime(0, $5, $4, $3, $2 - 1, $1 - 1900)."$6\n";' file

NAME
POSIX::strptime - Perl extension to the POSIX date parsing strptime(3) function SYNOPSIS
($sec, $min, $hour, $mday, $mon, $year, $wday, $yday) = POSIX::strptime("string", "Format"); DESCRIPTION
Perl interface to strptime(3) FUNCTIONS
strptime ($sec, $min, $hour, $mday, $mon, $year, $wday, $yday) = POSIX::strptime(string, format); The result for any value not extracted is not defined. Some platforms may reliably return "undef", but this is dependent on the strptime(3) function in the underlying C library. For example, only the following fields may be relied upon: my ($min, $hour) = ( POSIX::strptime( "01:23", '%H:%M' ) )[1,2]; my ($mday, $mon, $year) = ( POSIX::strptime( "2010/07/16", '%Y/%m/%d' ) )[3,4,5]; Furthermore, not all platforms will set the $wday and $yday elements. If these values are required, use "mktime" and "gmtime": use POSIX qw( mktime ); use POSIX::strptime qw( strptime ); my ($mday, $mon, $year) = ( POSIX::strptime( "2010/07/16", '%Y/%m/%d' ) )[3,4,5]; my $wday = ( gmtime mktime 0, 0, 0, $mday, $mon, $year )[6]; SEE ALSO
