Re: Date in Filename

Whatever method you use, I recommend dates in the sortable format: "YYYY-MM-DD.hh-mm-ss".

my @now = localtime();
my $timestamp = sprintf("%04d-%02d-%02d.%02d-%02d-%02d",
   $now[5]+1900, $now[4]+1, $now[3],
   $now[2], $now[1], $now[0]);
my $filename = "error.$timestamp.log";

I agree that dates should be in a sortable format. For filenames, I often use something like `YYYYMMDD_HHMMSS-filename`. It varies because sometimes I only need the date; sometimes I don't need seconds; etc. It doesn't much matter one way or the other, but I do think that, if human readablity is a goal, different separation characters for date components and time components are helpful. So, how about ISO 8601? `YYYY-MM-DDTHH:MM:SS`. Several CPAN modules already handle it... -sauoq "My two cents aren't worth a dime.";	[reply]
