Epoch time

Guys, i have a question...

I have 2 sets of data say "a" and "a+1" which has values in epoch time..

Question is... if i were to get the time difference where diff = "a+1" - "a"
can i convert it back to real time duration after the subtraction...
OR i need to convert em first before i do the subtraction to get the real time results in seconds and minutes...

Appreciate some light here...

thanks
Smilie

NAME
timetrans - Converts time into time SYNOPSIS
timetrans [units-options] [-count] DESCRIPTION
timetrans converts time from one type of unit to another. If any of the units options are specified, then timetrans will convert those time units into the number of seconds to which they add up. If given the count option, timetrans will convert that number of seconds into the appropriate number of weeks, days, hours, minutes, and seconds. The converted result is printed out. Units options cannot be specified in the same execution as the count option, and vice versa. timetrans is intended for use with DNSSEC-Tools, for calculating a zone's expiration time. OPTIONS
Units Options The converted value of each unit is totaled and a single result printed. -seconds seconds Count of seconds to convert to seconds. -minutes minutes Count of minutes to convert to seconds. -hours hours Count of hours to convert to seconds. -days days Count of days to convert to seconds. -weeks weeks Count of weeks to convert to seconds. Count Option The specified seconds count is converted to the appropriate number of weeks, days, hours, minutes, and seconds. -count seconds Count of seconds to convert to the appropriate set of units. Other Options timetrans has the following miscellaneous options. -Version Displays the version information for timetrans and the DNSSEC-Tools package. EXAMPLES
Example 1: Converting 5 days into seconds $(42)> timetrans -days 5 432000 Example 2: Converting 2 weeks into seconds $(43)> timetrans -w 2 1209600 Example 3: Converting 8 days and 8 hours into seconds $(44)> timetrans -d 8 -hours 8 720000 Example 4: Converting 1 week, 1 day, and 8 hours into seconds $(46)> timetrans -w 1 -days 1 -h 8 720000 Example 5: Converting 14 weeks, 4 days, 21 hours, 8 minutes, and 8 seconds into seconds $(47)> timetrans -w 14 -d 4 -h 21 -m 8 -s 8 8888888 Example 6: Converting 720000 seconds into time units $(48)> timetrans -c 720000 1 week, 1 day, 8 hours Example 7: Converting 1814421 seconds into time units $(49)> timetrans -c 1814421 3 weeks, 21 seconds Example 8: Converting 8888888 seconds into time units $(50)> timetrans -c 8888888 14 weeks, 4 days, 21 hours, 8 minutes, 8 seconds COPYRIGHT
