HTTP plots show time in UTC, not in local time

[tvoverbeek]

The plots in the HTTP output plugin show the time axis in UTC, not in local time.
Can easily be fixed by correcting for the local timezone offset:
Line 206 in http.py (in recordData function):
Change 't[0] = time.time()' to 't[0] = time.time() - time.timezone'

Hmmm. the suggested fix gives me a time which is one hour behind the correct time. Anyone got any ideas? Timezone isn't DST or anything silly.

Pythons time.time() returns seconds since epoch in UTC (which is right now OK in the UK).
For me in Austria the time was one hour off, hence the correction with time.timezone.
What are your Pis settings for local time and timezone?

OK, I've found the problem with the fix (although I don't have a fix for the problem with the fix!).

Adding " - time.timezone" as suggested has fixed the problem for the majority of timezones; this is included in 06c9352cec0fe91c89d1bb1258fcc2bac6d8c957. I've tested with timezones for Vienna, Buenos Aires and Hong Kong.

However, it still doesn't work for AEDT or ACDT in Australia; these are Daylight Saving timezones. The "Last updated" title of the page is correct with these timezones, but the graph data is one hour behind.

I suspect the key may lie somewhere around the try: block at line approx. 155, but haven't been able to nail it down yet.
