Add fix for local time bug

The test 'test_old_timestamp' was not able to pass in different
timezones due to hardcoded expected datetime

Change `test_alarm_processor.py` permissions

`test_alarm_processor.py` had different permissions than other test
files. While `unittest` module could collect tests in this file,
nosetests could't do it. Nose can collect tests in this file after
permissions change
