Comment 10 for bug 127505

Libra Office has take 12/31/1899 as 1 and not 1900 as base for caluclation
if we will format 01/01/1900 as number it will give you 2. There is no 0 base value. which is actully problem for all date based calculations. a base date is required for calulation. 12/30/1899 is used as 0. So first resolve the base vlaue proble then only date based calculation can be resolved
