Ooops, I didn't check to see if this reply would also get to the list. A 
copy now below.

Thank you Frank and thanks to all those who replied to my question.

(Frank, I think there is a typo in the first statement - with the "\n" 
in it - because I get an error message when trying to use it.)

I used the statement-

date --date=@<seconds>

to calculate the real date/time - this statement is the easiest to 
remember <g>.

I also used the URL, epoch_conversion, which Tony provided and this 
really created a big question mark about how reliable/accurate this 
calculation business really is.

By this I mean that using 'date --date=' for 1168396306 seconds I get-

10 January 2007 13:31:46 EST <================= NOTE: not EDT, daylight 
saving time, even though my clock is set to EDT

but when using the epoch converter I get this-

9 January 2007 09:31:46 GMT <===============epoch converter gives time 
as GMT

but this GMT time cannot be correct - unless I have missed something 
(never been good when dealing with time zones).

I also determined that in Firefox it is the local time (the time set on 
the computer) which is used to timestamp a bookmark when it is created 
and when the URL it represents is (last) accessed.

Again, thank you all for providing me with the (most valuable) information.
