Still looking at a time related bug. Wondering how (nowadays) linux handles TZ and DST/ST transition.
Does linux embed DST state into TZ? Or is there a variable with a name like "DST"? I want to set two different machines, one a PC, the other a dumb instrument to the same time. The dumb one doesn't do time adjustment. My PC, obviously does. I want to create a time, on my PC called: mytime = utc + utc_offset. If utc_offset is invariant, then I am all set. All I can see is (at least for ubuntu) there is TZ, which appears to be equal to utc_offset + DST*1. If there was a variable called DST, I'd be done. Then mytime = utc + utc_offset -DST*1, where DST=1 if now is daylight savings time, or DST=0 if now is standard time. Anyone have insight on this? All I know is that my dumb machine was set to DST last month. My PC is DST corrected. Half the time, (all during ST) the device clock is ahead of the PC clock. Why is this bad - because the PC refuses to read files timestamped in the future. I do not want to correct the dumb machine's clock twice a year, as there is documented potential for destroying data. This should be correctable on the PC end, shouldn't it? _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
