[Octave-bug-tracker] [bug #36954] datenum / datevec convert date-time string incorrectly during hour lost to DST

[Philip Nienhuis]

Follow-up Comment #15, bug #36954 (project octave):

Sure, my cset is a kludge but one that works for me.

First, I'm not so proficient in the internals of strptime and friends and when
I delved into this bug it soon appeared to me that time zones and DST
constitute a science on their own.
Furthermore apparently almost no one bothered about this bug for 5 years (the
original bug report is from 2012); admittedly it is a corner case that few
people hit.
Therefore I didn't delve into this all the way and fixed it just for my own
purposes.

Initially the code overhead was also a concern for me, but after looking into
datenum and datevec and finding how much code those functions need to do their
job I was quite a bit less alarmed :-)

But I agree that some timings may be helpful.  In my own experience I didn't
note significant performance hits.
