This question originated when I came upon (another thread) about Python's datetime and timedelta objects.

I followed the update by jimgardener and read the comments by eyquem ,and tried out some python code ..I am having a bad time understanding the way things work here(due to my newbie to python status)..I thought it was proper to ask a new question

import datetime
#for t1=23:30:00 PM
t1 = datetime.time(23,30,00)

#for t1=00:15:30 AM
t2 = datetime.time(0,15,30)

td1 = datetime.timedelta(hours=t1.hour,minutes = t1.minute,seconds=t1.second)

td2 = datetime.timedelta(hours=t2.hour,minutes = t2.minute,seconds=t2.second)

#substarcting timedeltas
tdiff = td2-td1

printing these variables yielded

td1 ==> datetime.timedelta(0, 84600)
td1.seconds ==> 84600

td2 ==> datetime.timedelta(0, 930)
td2.seconds ==> 930

tdiff ==> datetime.timedelta(-1, 2730)

When I looked at these results,I noticed that

td1.seconds (ie 84600) is equivalent to 
84600/60 ==> 1410 minutes
1410/60 ==> 23.5 hours
or in short,td1 represents the duration **from previous midnight** to 23:30 PM

now ,

td2.seconds (ie 930) is equivalent to
930/60 ==> 15.5 minutes or 15 minutes and 30 seconds
which means td2 represents the duration from **that midnight**
 to 00:15:30 AM

when tdiff is examined,I found that

tdiff ==> timedelta(-1,2730)
tdiff.seconds ==> 2730
tdiff.seconds/60 ==>45 minutes

this is the same as duration between t1(23:30:00 PM) and t2(00:15:30 AM) assuming that t2 follows t1

My question is,since td1 is the duration from previous midnight to 23:30:00 PM and

python datetime timedelta
