You need to clarify what you mean by hexadecimal format. If you are referring to
epoch seconds (seconds since 1-Jan-1970 00:00:00 UTC) then

perl -e 'print scalar localtime(1000)'

where 1000 = 1000 seconds after 1-Jan-1700 00:00:00

or if hex:
perl -e 'print scalar localtime(hex("0x1000"))'

Man perlfunc for more details.

Write a C program that takes the date in hexadecimal (presumably seconds since the Epoch?) and calls localtime() and strftime() to convert it into an ASCii string. Can't think of a way to do it in shell, probably is a smart way of doing it in Perl though.

Yes, i refer to epoch seconds (seconds since 1-Jan-1970 00:00:00 UTC).
Seconds in hex format.

# perl -e 'print scalar localtime(hex("0x4131d0ca"))'

output:
Sun Aug 29 14:49:14 2004
