Just force py2exe to include part or all of the pytz package, in my case 
I only need UTC so I do:

options = {"py2exe": {"compressed": 1,
                       "optimize": 2,
                       "packages": ["encodings",
                                    "kinterbasdb",
                                    "pytz.zoneinfo.UTC", 			 
                        "matplotlib.numerix",
                                    "email",
                                    ],
