Anyone find and answer to this... I am also having the same problem.
Output of putty:

and a screen shot of my ticket system:

I amusing HCL version 2.1.2, yes I am aware this is an older version, however I need the osTicket plug-in and this was the latest release with the osTicket module that I could find.
Also this isn't browser specific, tried Firefox, IE ... its the same on both.
I did reboot my server, at first the time said it was 7:00PM, as you can see in the picture I time traveled to the past because the date stayed the same, the time however is set at 2:00PM.
If this is cause by the php code (as mentioned in the above posts) where can I find this code at?
Thanks for your help.
