Another bug I have found is to do with daylight saving. In my setup I was getting daylight saving corrections, even though it is winter here in Australia.
Looking at the ospi.py code, I see
gv.lrun[3] = now-(time.timezone-(time.daylight*3600))and
homepg += 'n'I am no python programmer, so I looked up the time functions. It seems that time.daylight will return 1 in timezones that have daylight saving regardless of whether it is currently applied, so the above code segments will incorrectly adjust for daylight saving all year.
