how to compare file modification time in bourne shell script

[Andy Burgess]

I need to compare the modification times of two files in a bourne shell
script. I would like to do this without writing C code.
Machine is Sparcstation 1 running SunOS 4.03c

Thus I need a function:

newer file1 file2

that returns 0 if file1 is newer than file2 else returns 1

Can it be done?
