PERL - Alternative für localtime (millisekunden)

[_m3]

perldoc -f time
time Returns the number of non-leap seconds since whatever time the
system considers to be the epoch (that's 00:00:00, January 1,
1904 for MacOS, and 00:00:00 UTC, January 1, 1970 for most other
systems). Suitable for feeding to "gmtime" and "localtime".

For measuring time in better granularity than one second, you
may use either the Time::HiRes module from CPAN, or if you have
gettimeofday(2), you may be able to use the "syscall" interface
of Perl, see the perlfaq8 manpage for details.
