Sounds like your time zone is not set in your php.ini file. Try following this thread to see if it solves your issue.

I presume you have a mod installed as this doesn't occur in original Hesk?

If everything works well you can usually ignore notices; make sure "debug mode" is turned off in Hesk settings.
