What OS and shell do you work on?

OS = AIX oslevel:7.1
SHELL = KSH

Which version(s) of ksh do you have on AIX 7.1?

What output do you get from:
Code:
ksh --version
ksh93 --version

I'm not sure if 93t+ is recent enough to support this... What output do you get from the command:
Code:
printf '%(%Y-%m-%d@%H:%M:%S %s\n)T' '12/28/17 0:40' '12/27/17 23:20'

In the US Pacific timezone, it should give you:
Code:
2017-12-28@00:40:00 1514450400
2017-12-27@23:20:00 1514445600

In other timezones, the last number on each line will be different (but the difference between those numbers will be a constant... the number of seconds between those two times).

If you do get output similar to the above, does that give you enough information to solve your problem?

This is what i get

Code:
# printf '%(%Y-%m-%d@%H:%M:%S %s\n)T' '12/28/17 0:40' '12/27/17 23:20'
(Y-%d@%M:%s
)T
