Then, you could keep using DateTime::Format::Strptime (with %z), or use DateTime::Format::RFC3339. For example, using the standard RFC3339 format, you could use any of T02:30:00-05:00įor the former and any of T02:30:00-06:00įor the latter. 02:30:00 -06:00 (America/Denver) After "fall back"ĭate-times should be transmitted in UTC or provide the offset from UTC of the date-time. Start: Mountain Standard Time (MST) starts on Sunday, Novemat 2:00 am local time. Standard time ends annually the on second Sunday of March. CST (China Standard Time) is 5 hours ahead of Moscow Standard Time 9:30 am 09:30 in Daye, China is 4:30 am 04:30 in MST. For one hour every year, you'll get the wrong answer due to the overlap during the DST change.Ĭould refer to both 02:30:00 -05:00 (America/Denver) Before "fall back" End: Mountain Standard Time (MST) has ended on Sunday, Maat 2:00 am local time and clocks were set one hour forward to Sunday, March 13, 2022, 3:00 am local daylight time instead. Maybe you meant to use US Mountain Time, which is identified by America/Denver (UTC-7 in winter, UTC-6 in summer). Is therefore 10:00:00 -07:00 (America/Los_Angeles)ĭateTime properly converted the date-time. The correct conversion of 10:00:00 -07:00 (MST) The time difference between Coordinated Universal Time (UTC) and Mountain Standard Time (MST) is 7 hours. US Pacific Time ( America/Los_Angeles) is UTC-8 in the winter, and UTC-7 in the summer. Mountain Standard Time is seven hours behind the Coordinated Universal Time standard, written as an offset of UTC - 7:00.US Mountain Standard Time ( MST) is UTC-7.If you refer to this list of tz database time zones, you'll see that In MST, this will be a usual working time of between 9:00 am and 11:00 am. If you are in UTC, the most convenient time to accommodate all parties is between 4:00 pm and 6:00 pm for a conference call or meeting. But even if the date-time is in US Mountain Time, that won't always give you the right answer. When planning a call between UTC and MST, you need to consider time difference between these time zones. I think you meant to use US Mountain Time, which is identified by America/Denver.
