Greg, I think your complaints are unfounded. Right under the field in the Vehicle config page where you enter the timezone are two web links, the first giving a list of strings for various locations and the second pointing to the specification for the string. This tells the user what input is expected. Now, I concede this is not perfect because in the first link the US/Canada strings are not complete (e.g. just "PST8PDT" rather than "PST8PDT,M3.2.0/2,M11.1.0") and I don't know what the code does in that case. Perhaps we can find another link that gives the complete strings for a more complete list of locations. And the second link is fine for geeks but may not be for the average user. Furthermore, I think your expectation that most people understand their timezone in numerical format is not correct. Even those who know that the difference between PST and GMT is 8 hours might be uncertain whether they should enter 8 or -8. And many do not know whether DST means that number should be 7 or 9. Just as a test, I asked my wife; she did not know. And for anyone using OVMS for scheduling, having it not handle the DST shift automatically is a real liability. If we did accept a simple numeric format, users in zones with DST would have to change the config twice a year. That's a pain. I compare it to the cheap little DVR box I use. It requires that I set or clear a DST checkbox at the beginning and end of summer. More than once I have forgotten this and missed my intended recording. -- Steve
