|
# 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'. |
