Q&A > dates and times > How do I incorporate a timestamp into a file name? - Answer contributed by mikeB

# grab the current time my @now = localtime(); # rearrange the following to suit your stamping needs. # it currently generates YYYYMMDDhhmmss my $timeStamp = sprintf("%04d%02d%02d%02d%02d%02d", $now[5]+1900, $now[4]+1, $now[3], $now[2], $now[1], $now[0]); # insert stamp into constant portion of file name. # the constant portion of the name could be included # in the sprintf() above. my $fileName = "File$timeStamp.log";
