1 ;# ctime.pl is a simple Perl emulation for the well known ctime(3C) function.
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
