Hello Everyone.
 
I am new to *nix in general, and so when I ran across unix-time for the first time, I took the time to read up on it.  I have created a wifi captured portal system using freeRADIUS, Mysql and Open BlueDragon, but I am having a problem with the Expiration attribute in freeRADIUS.  Admittedly, the problem is probably DEU (defective end-user), so I am hoping someone here can help me out.
 
Do I have to use the Unix-time for the Expiration attribute, or do I have a more human-readable option?  I tried various standard database and programming timestamp values, but freeRADIUS always returns a "can't parse date" error whenever I use anything but unix-time.
 
If I must use unix time, which I understand is GMT zulu, should I pass my expiration dates to the database in GMT zulu as well? Is freeRADIUS taking my (Pacific Time) offset into account which is set on the server?
 
I took the time to write some time conversion code in CFML, so I am ready to go as soon as I can figure out what the freeRADIUS server expects of me.  I spent a lot of time the last couple days looking around online, and subsuquently learned quite a bit more on this subject, but never found a solution to my problem.
 
OS: Ubuntu Server 8.04
freeRADIUS version: 1.1.7-1build4 (the version apt installs for Hardy)
mySQL: 5.0.51a-3ubuntu5
 
Thanks in advance, and have a great Sunday night.
