Decoding Time Fields
Time fi elds are based on a simple mathematical relationship. The number represents
the time that has elapsed since midnight December 30, 1899, in days. For example:
Time Value Represents
0.25 Dec 30, 1899 6:00 AM
0.75 Dec 30, 1899 6:00 PM
1.5 Dec 31, 1899 Noon
365.25 Dec 30, 1900 6:00 AM
35065.625 Jan 1, 1996 3:00 PM
The integer portion of the number represents the number of days that have elapsed
since Dec 30, 1899. The fractional portion is the fractional part of a day (0 is midnight,
0.5 is noon and 0.9999884 is one second before midnight).
This is a time format used in several applications. For example, if these numbers
are imported into Excel for Windows they can be directly converted into time and
date with the sequence:
Format, Cell, Modify, Number, Date, m/d/yy h:mm.
Note: The column width will have to be adjusted to display the day and date
correctly.
