Is there a better way to do this? def SkewTime(): ''' Optional function. We can skew time by 1 hour if we'd like to see real sync changes being enforced ''' TIME_SKEW=1 logging.info('Time Skewing has been selected. Setting clock ahead 1 hour') # Let's get our current time t = TimeCheck() logging.info('Current time is: %s' % time.asctime(t)) # Now create new time string in the form MMDDhhmmYYYY for the date program hr = t.tm_hour + TIME_SKEW date_string = time.strftime('%m%d%H%M%Y',(t.tm_year, t.tm_mon, t.tm_mday, hr, t.tm_min, t.tm_sec, t.tm_wday, t.tm_yday, t.tm_isdst)) logging.debug('New date string is: %s' % date_string) logging.debug('Setting new system time/date') status = SilentCall('/bin/date %s' % date_string) logging.info('Pre-sync time is: %s' % time.asctime())
TimeCheck() as referenced above is a simple function that just returns the time.time_struct object from time.localtime(). I pull time a few times and it was a little cleaner to put that into a function and just call the function whenever I needed to. SilentCall() is a modification of subprocess.call() (which in reality just calls Popen(*popenargs,**kwargs).wait()) but it defaults to redirecting stdin and stdout to /dev/null to suppress shell output from the command being called. Anyway, what I'm wondering, is, while this works, is there a better way to do it than using part of the originally returned time_struct and injecting my own new hour argument (hr). The goal of this function is to just set the system clock one hour ahead, so when I call the Linux command 'ntpdate' I can get a real time change when it syncs the local clock to an NTP server. This just looks... well, big to me. I tried passing only the things I really needed to time.strftime(), but apparently, that requires the full 9-tuple from time_struct, not just individual parts of it. Like I said, it works well, I just wonder if there is a cleaner way of setting the local clock to a different time in python without having to do all this. The reason most of that exists, is because the linux date command expects to see the new date/time like this: MMDDhhmmYYYY.ss. Or am I just looking at this too hard and really did work it out nicely?
