If your machine knows that local timezone is equivalent to UTC, which
I believe it is during the winter, then the Python routines will take
this string without zone indicator as UTC.

Naively(*) my mileage would vary at any time of year, and yours
should vary during the summer.

(*) In my code I take pains to ensure that when I am using
off-the-shelf date parsing code I have that thread operate
in an environment which I have explicitly reset to UTC.
