ValueError: time data '2014-09-19 15:51:55 +0100' does not match format '%Y-%m-%d %H:%M:%S +0000' while building Glyphs_Sapperlot.glyphs

[marekjez86]

I built the pipeline in the morning (PDT) on 2016-02-12.
I found Glyphs_Sapperlot.glyphs in https://github.com/DrTypo/sapperlot and decided to try using it as an input to the pipeline (my mac glyphs.app can export unhinted OTF files from Glyphs_Sapperlot.glyphs).

We get the following error while running the pipeline:

==== building src/Glyphs_Sapperlot.glyphs ====

[adrientetar]

In datetime.strptime(string, '%Y-%m-%d %H:%M:%S +0000') replace +0000 with %z.

[jamesgk]

%z is not supported on all platforms in Python 2 (see http://bugs.python.org/issue6641), I think I'd rather just chop off the timezone for now.

[adrientetar]

I couldn't find which platforms are affected. Then:

string, tz = string[:-6], string[-4:]
dt = datetime.datetime.strptime(string, '%Y-%m-%d %H:%M:%S')
return dt + datetime.timedelta(hours=int(tz[:2]), minutes=int(tz[2:]))
