hp-unix stat command to get last change date of file

I'm on hp-unix. I would like a variable to hold the last change date of a file. I looked at the man pages for stat, but I don't see any examples and can't get the syntax right. Can anyone help me? Thank you.

Try this,

 perl -e 'print (scalar localtime((stat($ARGV[0]))[9]),"\n");' filename

If you have GNU coretuils installed, then there is a stat command (not a C system call) that works from the command line. Otherwise you have to resort to perl or C.

what does that output of

which stat

show?
