mktime() and gmtime() are not inverses of each other. The first assumes local
time, and the latter gmt (or utc). So unless you happen to be in England, and
not in daylight savings time, you'd expect a problem.
mktime() is documented as the inverse of localtime(), according to the docs.
I'd assume they'd both make the same time adjustments for your location.
However, there's some ambiguity if the time you're looking at is in standard
time, while you're currently in daylight savings. So I'd look for an answer
that only used UTC (or Greenwich Mean time).
Try time.gmtime(), and calendar.timegm()

I need to add one minute to a string that has a date and a time in
YYYYMMDDHHMM format.
e.g: 200903281346 should become 200903281347
the following script converts the string into time and adds one
minute; but somehow I also add an hour and I don't understand why.
====================
import time
#set the initial time as a string and convert it into time format:
fromtimestring = '200903281346'
fromtimetime = time.strptime(fromtimestring, "%Y%m%d%H%M")
#convert this time format into UNIX time (seconds since the start of UNIX time):
fromtimeseconds = time.mktime(fromtimetime)
#add 60 seconds and reformat the result into the YYYYMMDDHHMM format
totimeseconds = fromtimeseconds + 60
totimetime = time.gmtime(totimeseconds)
# convert the new time into a string:
totimestring = time.strftime("%Y%m%d%H%M", totimetime)
#print the results:
print (fromtimestring)
print (fromtimetime)
print (totimetime)
print (totimestring)
================
any help or suggestions would be much appreciated.
