Comments

A variant time is stored as an 8-byte real value (double), representing a date between January 1, 1753 and December 31, 2078, inclusive. The value 2.0 represents January 1, 1900; 3.0 represents January 2, 1900, and so on. Adding 1 to the value increments the date by a day. The fractional part of the value represents the time of day. Thus, 2.5 represents noon on January 1, 1900; 3.25 is 6:00 a.m. on January 2, 1900; and so on. Negative numbers represent the dates prior to December 30, 1899.

See the Comments section of "DosDateTimeToVariantTime" for a description of the MS-DOS date and time formats.
