dthacker has asked for the wisdom of the Perl Monks concerning the following question:

I've have a program that copies files from a log directory to an archive directory and appends a date stamp to the end of the filename. After looking at some other code locally I used this sub to create the datestamp:
sub get_time_stamp() { my @tan=Today_and_Now(); my $stamp=join '', @tan[0..4]; return $stamp; }

Unfortunately this is giving me YYYYMDDHHMM instead of YYYYMMDDHHMM. Is there a more effective way of getting the string I want than padding the output of  Today_and_Now?

    i'd recommend sprintf here:
    sub get_time_stamp() { my @tan=Today_and_Now(); my $stamp= sprintf '%d%02d%02d%02d%02d', @tan[0..4]; return $stamp; }
    or the brief version:
    sub get_time_stamp() { sprintf '%d%02d%02d%02d%02d', (Today_and_Now())[0..4]; }
    this will keep all all the potential 1 or 2 digit fields padded with a zero. cheers, - danboo
Re: Creating a date stamp (Russ: POSIX::strftime)

    Look at POSIX::strftime. You provide a format string (similar to sprintf) which would look very similar to the format strings you gave as examples :-)
