Python function to take GPS week and GPS seconds and return a UTC datetime string in the format "YYYY-MM-DD HH:MM:SS"

GPStoUTC.py

def weeksecondstoutc(gpsweek,gpsseconds,leapseconds):
    import datetime, calendar
    datetimeformat = "%Y-%m-%d %H:%M:%S"
    epoch = datetime.datetime.strptime("1980-01-06 00:00:00",datetimeformat)
    elapsed = datetime.timedelta(days=(gpsweek*7),seconds=(gpsseconds+leapseconds))
    return datetime.datetime.strftime(epoch + elapsed,datetimeformat)
    
weeksecondstoutc(1811,164196.732,16) ## --> '2014-09-22 21:36:52'
