Hi, does anyone happen to know of a script that would return the
number of seconds in a month if I give it a month and a year?
My python is a little weak, but if anyone could offer some suggestions
I think I could handle it myself, or if anyone happens to know of a
script already written that performs this I would be extremely
grateful.
Thanks!

Probably there are sophisticated answers, but have you tried
something like:
monthDays={'Jan ':31,'Feb':28, ..}
secs=60*60*24*m onthDays[thisMonth]
if (thisMonth=='Fe b'
and isLeap(thisYear )):
secs+=60*60*24
return secs
?

something like this might work, it should event handle DST correctly.
You could read up on mktime() if you want to make sure.
from time import mktime
def secondsInMonth( year, month):
s1 = mktime((year,mo nth,1,0,0,0,0,0 ,-1))
s2 = mktime((year,mo nth+1,1,0,0,0,0 ,0,-1))
return s2-s1
/Matt
Mattfrom time import mktime
Mattdef secondsInMonth( year, month):
Matt s1 = mktime((year,mo nth,1,0,0,0,0,0 ,-1))
Matt s2 = mktime((year,mo nth+1,1,0,0,0,0 ,0,-1))
Matt return s2-s1
Probably won't work if month==12. ;-)

Do you need to handle leap seconds too? (not a joke)
-- Paul
Jim: I need years too, basically from 1960-2000. Don't want to
hardcode all those days :)
Matt: Thanks, I will try this out.
Paul: I don't believe we need leap seconds. Leap days definitely.
I'll let you know how Matt's code works. Any other suggestions feel
free to let me know.
Thanks all!

Actually, mktime as described in the C Standard does not
restrict members such as tm_mon of struct tm to the
range 0-11 (1-12 for the corresponding entry in the
time tuple in Python). So the underlying struct in
CPython may be normalized and return a perfectly valid
time even if month is 12.

Dear all,
Do any one have idea how to obtain the exactly number of seconds in a month
with given month and year using DB2 given functions?
The formula is as simple as "No_of_days_for_a_month" * 60 * 60 * 24 .. but
It is a headache for me to find the No_of_days_for_a_month... in DB2
Thanks very much!

Does anything about this script look expensive, in terms of resources or
execution time? This script dies after processing about 20 or 25
numbers, yet it leaves no errors in the error logs. This is on a server
that handles a fairly demanding site. The defaults, in php.ini, have all
been cranked fairly high: scripts get 180 seconds to run, and they can
have as much as 256 megs of RAM.
