How to translate Excel dates to perl

by  prex1  Posted    (Edited  )
Excel stores dates as serial numbers, representing the number of days past one of two optional starting dates (the default in Windows is 00 Jan 1900, as day one is 1 Jan 1900).
Perl uses the number of seconds past the 'epoch', and the epoch on most systems is 1 Jan 1970.
To translate an Excel serial number to perl time, when the reference dates are the defaults as above, use the following
Code: 
print scalar gmtime(($ExcelDate-25569)*86400);
This will display something like [tt]Fri Jul 27 09:39:11 2007[/tt], but may be rearranged by using the list output of [tt]gmtime()[/tt] or [tt]localtime()[/tt])
