Woops that would help wouldn't it :-)

I'm running 5.2 that was installed from the CD.

I should have included some history, I wasn't thinking clearly at the
time of the original mail.

Everything worked fine until I decided to upgrade gcc which I did from a
6.2 CD. I also upgraded Perl to the one from the RH6.2 CD. I did this so
I could compile and run MRTG since its doc claimed that Perl was broken
under 5.2 and after I compiled MRTG the "rateup" binary exhibited some
weirds which caused me to think I might need to upgrade gcc too.

Same deal and all calls to date functions return random values too ie:
if I "touch" a file the resultant mod date and time is random.

Here is the output from that:

Comments? ideas ?

I surmise that one of the libs is broken and I not sure how to fix this.

My first thought is to go back to the previous version of gcc or is
there a more recent one again that I should upgrade to ?

thanks
