b1248f16 1;# ctime.pl is a simple Perl emulation for the well known ctime(3C) function.
a6d71656 2#
3# This library is no longer being maintained, and is included for backward
4# compatibility with Perl 4 programs which may require it.
5#
6# In particular, this should not be used as an example of modern Perl
7# programming techniques.
8#
9# Suggested alternative: the POSIX ctime function
