$ python2 -c 'import datetime; print datetime.time(10, 44, 11).strftime("%s")'

$ python3 -c 'import datetime; print (datetime.time(10, 44, 11).strftime("%s"))'

So apparently, datetime.time(...).strftime("%s") semantically "seconds since unix epoch" assumes Jan 1, 1900 for missing date part.

However datetime module doesn't allow subtracting time objects, i.e. no assumption of date is made, where "same date" chould be reasonable.

I believe this is effectively a duplicate of issue 12750.  That is, python doesn't do anything in particular with %s, it just lets the platform do what it will.  Issue 12750 is about making what it does consistent and cross-platform.

(On gentoo linux I get -1 from your examples for both python2 and python3.)

You should any any further comments to issue 12750.
