Linux or Windows?
In Windows, some characters are not allowed in file names. I do believe
':' is one of them (it is use to separate the volume from the path as in
C:\TEMP).
BTW, you may want to investigate strftime() in POSIX. It formats dates:
use POSIX;
my @tm = localtime;
$Date = strftime( '%m_%d_%Y_%H_%M_%S', @tm );
