I think the GBA patch application GBATA (can be found in the downloads section here) has a patch that can hack the real time clock. Not sure if it will work on this emulator, but give it a try anyways, I've used it on VBA and it seems to work well.

Just load the rom in the utility, I think the clock fix will help you.
