-#
-# UNIX/Perl time is the time since the Epoch (00:00:00 GMT, 1 Jan 1970)
-# measured in seconds.
-#
-# An Excel file can use exactly one of two different date/time systems.
-# In these systems, a floating point number represents the number of days
-# (and fractional parts of the day) since a start point. The floating point
-# number is referred to as a 'serial'.
-# The two systems ('1900' and '1904') use different starting points:
-# '1900'; '1.00' is 1 Jan 1900 BUT 1900 is erroneously regarded as
-# a leap year - see:
-# http://support.microsoft.com/support/kb/articles/Q181/3/70.asp
-# for the excuse^H^H^H^H^H^Hreason.
-# '1904'; '1.00' is 2 Jan 1904.
-#
-# The '1904' system is the default for Apple Macs. Windows versions of
-# Excel have the option to use the '1904' system.
-#
-# Note that Visual Basic's "DateSerial" function does NOT erroneously
-# regard 1900 as a leap year, and thus its serials do not agree with
-# the 1900 serials of Excel for dates before 1 Mar 1900.
-#
-# Note that StarOffice (at least at version 5.2) does NOT erroneously
-# regard 1900 as a leap year, and thus its serials do not agree with
-# the 1900 serials of Excel for dates before 1 Mar 1900.

-# Calculation description
-# =======================
-#
-# 1900 system
-# -----------
-# Unix time is '0' at 00:00:00 GMT 1 Jan 1970, i.e. 70 years after 1 Jan 1900.
-# Of those 70 years, 17 (1904,08,12,16,20,24,28,32,36,40,44,48,52,56,60,64,68)
-# were leap years with an extra day.
-# Thus there were 17 + 70*365 days = 25567 days between 1 Jan 1900 and
-# 1 Jan 1970.
-# In the 1900 system, '1' is 1 Jan 1900, but as 1900 was not a leap year
-# 1 Jan 1900 should really be '2', so 1 Jan 1970 is '25569'.
-#
-# 1904 system
-# -----------
-# Unix time is '0' at 00:00:00 GMT 1 Jan 1970, i.e. 66 years after 1 Jan 1904.
-# Of those 66 years, 17 (1904,08,12,16,20,24,28,32,36,40,44,48,52,56,60,64,68)
-# were leap years with an extra day.
-# Thus there were 17 + 66*365 days = 24107 days between 1 Jan 1904 and
-# 1 Jan 1970.
-# In the 1904 system, 2 Jan 1904 being '1', 1 Jan 1970 is '24107'.
