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). --keith -- kkeller-usenet(a)wombat.san-francisco.ca.us (try just my userid to email me) AOLSFAQ=http://www.therockgarden.ca/aolsfaq.txt see X- headers for PGP signature information

Wouldn't it have been better to point the OP to POSIX::strftime() and drop that rant? -- Gunnar Hjalmarsson Email: http://www.gunnar.cc/cgi-bin/contact.pl

I thought I was just being complete. Thanks for the pointer to POSIX::strftime; I seldom use the POSIX:: modules. --keith -- kkeller-usenet(a)wombat.san-francisco.ca.us (try just my userid to email me) AOLSFAQ=http://www.therockgarden.ca/aolsfaq.txt see X- headers for PGP signature information |
