Calculating time differences given daylight savings time using Python

+5 votes
380 views

I am running Python 2.7 and would like to be able to calculate to the second the time difference between now and some future date/time in the same timezone while taking into account daylight savings time. I do not have pytz. Any ideas how to do it?

If it requires having pytz, how would I do it with pytz?

I am using 2.7. I need to print the time in seconds from the epoch with millisecond precision. I have tried many things but have failed.

 from time import time, strftime
 from datetime import datetime, time

 # write date, time, then seconds from epoch
 self.logfile.write('%st'%(strftime("%Y-%m-%d",)))
 self.logfile.write('%st'%(now.strftime("%H:%M:%S",)))
 self.logfile.write('%st'%(now.time()))

What am i doing wrong? What should I be doing here?

I am able to see the absolute (exact) time on Win-XP of a file when it was last modified in hours, minutes, and seconds ("Today, May 11, 2014, 6:06:09 AM") by displaying the file properties.

On Windows 7, it displays the time as relative and a rough estimate ("Today, May 11, 2014, 2 hours ago"). How do I change it so it displays absolute time like Windows XP.

This function limits the"execution time" for a script. Is this CPU time or elapsed (wall-clock) time?

I'm asking because I'm running Win7 in a VirtualBox VM under OS X Mavericks. I've got an app that runs a number of scripts, using PHP 5.5.9. All runs correctly, but quite slowly, and a one script reports taking 20 secs or so of elapsed time when I might have expected 2 or 3 at most (as the same script running under OS X does).

I know that there is a note in the online doc for this function that says that under windows, extra time such as database calls is included. Would that include SQLite calls which wouldn't be included for the OS X version?

I've got a windows user whose scripts are actually running out of time, so I may have to add a php_value to the apache config to crank up the time limit.
