Simplelog lookup problems

[BSOD2600]

Since the latest simplelog only finds the most recent logons for a person, I've having troubles looking into the past months. I've tried:
+log nick [RU]Pennarts time 040101,040312
+log -v nick [RU]Pennarts time 04

Nothing seems to work. Whats the proper format and maybe the documentation needs a little work on how to properly use it...
