That is because localtime is a core function. You can find its docs
in the normal perldoc:
from perldoc -f localtime
Converts a time as returned by the time function to a 9−element
list with the time analyzed for the local time zone. Typically
used as follows:
# 0 1 2 3 4 5 6 7 8
($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime(time);
All list elements are numeric, and come straight out of the C
‘struct tm’. $sec, $min, and $hour are the seconds, minutes,
and hours of the specified time.
