+#
+# 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.
