What is the data structure for the UNIX time offset variables. If you do a man on time, you will see that time.h is the include file where these data structures are defined. (some are long ints, some are ints).
You can do a little homework on the data structure, post the results, if you don't mind? Thanks. The approach is to take the lenght of the integers and simply calculate what happens as the variables are converted between time subfunctions. You should be able to do this (with system call source code) quite easily.

Hi all,
I got a file with epoch times like this.
1264010700
1264097400
1263529800
1263762900
1263924300
What I want.
I want all epoch times which are > current epoch time written to a file. So everything that is < will be ignored and not written to the file.

sum
sum(1B) SunOS/BSD Compatibility Package Commands sum(1B)
NAME
sum - calculate a checksum for a file
SYNOPSIS
/usr/ucb/sum file...
DESCRIPTION
sum calculates and displays a 16-bit checksum for the named file and displays the size of the file in kilobytes. It is typically used to
look for bad spots, or to validate a file communicated over some transmission line. The checksum is calculated by an algorithm which may
yield different results on machines with 16-bit ints and machines with 32-bit ints, so it cannot always be used to validate that a file has
been transferred between machines with different-sized ints.
USAGE
See largefile(5) for the description of the behavior of sum when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWscpu |
+-----------------------------+-----------------------------+
SEE ALSO
sum(1), wc(1), attributes(5), largefile(5)
DIAGNOSTICS
Read error is indistinguishable from EOF on most devices; check the block count.
NOTES
sum and /usr/bin/sum (see sum(1)) return different checksums.
This utility is obsolete.
