Screen locker quirk

[farscape1a]

Good morning everyone. I have a little bit of a quirk that i'm trying to nail down, but i'm having a little trouble. When my screensaver comes on as just a blank screen, it does not prompt for a password immediately, which is not what I'm looking for. I'd like for it to lock the screen immediately (or within 5 seconds). I've let it sit for 20 - 30 min, but it never asks for my password. Only when I've let it sit overnight does the password box come up (also with the incorrect time, 4 hours ahead in fact). How does one go about setting the lock timeout?

Thanks much!

Edit: Sorry, using MATE...
