Judging by the script, he's there until 4 a.m., not for 4 hours.

At least in the Enhanced Edition, it's possible to advance time by using the console command  – one hour for each use. (Not sure, this command works in the original game.) EE Keeper also has an option to set game time.

Leaving and reentering the area isn't necessary for him to appear.
