invalid time - why ?

[fowlertrainer@anonym.hu]

Hello python-list,
starttime=time. time()
.... process ....
endtime=time.ti me()
dtime=endtime-starttime
print "Started at:", time.strftime(" %H:%M:%S",time. localtime(start time))
print "Ended at:", time.strftime(" %H:%M:%S",time. localtime(endti me))
#print time.localtime( dtime)
print "Deltatime: ", time.strftime(" %H:%M:%S",time. localtime(dtime ))

My problem is in the result:

What I do wrong ?

The deltatime hour section is wrong. But why ?


Thanx.

Python like most operating system use seconds since 1970 for storing the time.

If you do "endtime-startime" your result will surely by in the year 1970.

You could do:
print "Deltatime %s hours" % float(dtime)/(60*60)

The extra hour comes from your timezone being Middle European Time (1 hour
ahead of GMT) whereas the Unix epoch starts on Jan 1, 1970, 00:00:00 GMT.
The displayed results of your script will vary with the timezone used when
you execute it.
To fix it, replace time.localtime( ) with time.gmtime() in the above.
Otherwise your approach should work as long as you are displaying time spans
that amount to less than 24 hours.
