I need to set a device to Hawaii’s HAST time zone. Before I go with what seems right to me, I would like a reality check on the why and how of it.
The why: The manual for my 4248 sez… “Default is set to: MTZ+6MDT+5,M4.1.0,M11.1.0. MTZ+6MDT+5. This indicates a time zone with 6 hours offset with 1 hour ahead which is U.S central time.” Isn’t that backwards? US Central time is behind UTC or UTC MINUS. Specifically, it is UTC -6/-5. UTC +6/+5 is around central Russia.
The How: Hawaiian Standard time is UTC -10. To set my gateway to HAST (and there is no HADT, making it simpler). I would expect to set it to MTZ-10 with no further parameters. Following the logic from the 4248 manual, should I set it to MTZ+10?
Also, with no DST, is that single statement all I need? The rest of the default setting (MDT+5,M4.1.0,M11.1.0) is all DST config.
