ambiguity in time indications #286

Open wwortel opened 1 year ago

wwortel commented 1 year ago

When tracking a sonde the left column shows details like DATETIME(LOCAL) BURSTTIMER

For those living near a timezone border this is ambiguous. It is unclear whether the 'LOCAL' is referring to where the sonde is, where it was launched, or where the person watching is located. Moreover it is unclear whether the times respect daylight saving time. The same applies to the burst timer. Also the help text leaves open what time standard is used for the moment the transmitter will be switched off.

Would advocate to indicate everything in UTC, and to introduce the choice to indicate all times in local time, being what the device uses that is applied to watch the Sondehub tracker site.

I don't necessarily agree with UTC-as-default. I agree an option to set all times to show as UTC would probably be useful however.

Local time is whatever your computer thinks is local time. We have no control over what this is. If your computer time is observing daylight savings time, then thats what its going to show.

As a note, burst timer is a countdown timer ('time until the radiosonde will be switched off'), not an absolute time, so would be unaffected by any changes.
