How to print formatted (!) the current timestamp? Thomas Blabb 05-04-2008

 I want to print the current time(stamp) in formatted style.
The following does not work:

print STDOUT "Now=%Y%m%d-%H%M\n", localtime(time);

What is wrong?

How else can I print out a formatted timestamp?

Tom

Try

use POSIX qw(strftime);
print strftime "%Y%m%d-%H%M\n", localtime;

Did you read perldoc -f localtime?

If you are happy with localtime's formatting, simply print it as a
scalar:

print scalar localtime();

If you want to use a print-equivalent statement to do your formatting,
you need to use printf. Also, perl date formatting has nothing to do
with UNIX date; %Y for example is the hash named Y, and bears no
relation at all to your call to localtime. Read perldoc -f sprintf for
valid formats (%Y is certainly not one).

Wouldn't it have been better to point the OP to POSIX::strftime() and
drop that rant?

Was I ranting? I thought I was just being complete. Thanks for the
pointer to POSIX::strftime; I seldom use the POSIX:: modules.
