Install of backup copy admin error

[phpman]

Hello All,

i copy a backup of a GS 3.3.1 site to my server again and i get the following
result. Page working but i can not login into the admin panel.

If i type username + password i get only a empty page.

If i use debug mode i get the following (not more)

Code:

Warning: admin_email(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.
