how to convert format of date to 'os.utime()' format

Question

I'm trying to convert an ordinal dateTime value into a value that can be accepted by os.utime()

My date has the format: 201642322295

(which is: year=2016, month=4, day=23, hour=22, minute=29, second=5)

However, the method won't accept this and I'm not sure how to/ what to convert it into. I've tried converting it into a datetime also but this does not work.

The code segment:

s = int(self.newTime)
date = datetime(year=s[0:4], month=s[4], day=s[5:2], hour=s[8:2], minute=s[10:2], second=s[12])
os.utime(self.fileName, (date,date))

(I had tried using just the ordinal format, which modifies the datetime of the file but is not at all correct)

edit: This is not the same as 'python converting datetime to be used in os.utime' because it's using a completely different format

os.utime expects values in the form of integers representing a untix timestamp.

s = int(self.newTime)
date = datetime(year=s[0:4], month=s[4], day=s[5:2], hour=s[8:2], minute=s[10:2], second=s[12])
utime = time.mktime(date.timetuple())
os.utime(self.fileName, (utime, utime))

Thank you. I'm a little closer but now I have a typeError: 'long' object has no attribute '__getitem__' – Jonathan H Apr 26 '16 at 00:51
well, you're casting `self.newTime` to an `int` and then trying to get substrings out of it to create your datetime. That's definitely incorrect. – Hamms Apr 26 '16 at 00:56
what is `self.newTime`? – Hamms Apr 26 '16 at 00:56
it was originally a string: 'datetime.datetime2016 4 23 22 29 5' , that I took out of a database query, and then I cut that down to just '201642322295' – Jonathan H Apr 26 '16 at 00:59
Oh right, of course! I was changing the code around so much I'd forgotten I changed it to an int – Jonathan H Apr 26 '16 at 01:01
a pretty standard development hiccup. :) is everything working now? – Hamms Apr 26 '16 at 01:02
yep, working like a beauty! – Jonathan H Apr 26 '16 at 01:20
