Margo,

Time is stored as a fraction of 1 day, dates as the number of date from
01/01/1900. Today, 9:00PM has a value of 38,356.88.

If your number is in seconds, divide it by 86,400 (24*60*60) to get a
date/time number.

I have some system logs that have a number that is either a serial number
or
the number of seconds. I have tried to use the Convert function, format
the
cell to date/time, but it doesn't look reasonable. I've read that serial
numbers start at 1/1/1900, but this would put my date/time at september
2005,
and we aren't there yet. :) Any suggestions and ideas would be
helpful.88
