I hate bringing this up, because DST can be such a mind #$%$. But here we go:
I have declared a Kendo datetimepicker like so:
.Format("yyyy/MM/dd HH:mm zzz")
I'll be using MST as my example timezone, ie. -6:00 or -7:00. On November 1st @ 2:00 AM time goes backwards 1 hour. So basically the time one second after 1:59:59 AM (-06:00) becomes 1:00:00 AM (-07:00)
The KendoDateTimePicker seems to be smart enough to recognize the timezone change. For example, selecting November 1st 00:30 (pre-time change) will show a timezone of (-06:00), and selecting November 1st 02:00 (post time change) will show a timezone of (-07:00)
The tricky part with the November time change is that there are two occurrences of 01:00:00 - 01:59:59 during that day. The first occurrence has a timezone of -06:00 and the second has a timezone one less, of -07:00. So the question is, how do I select one occurrence or the other, without having to manually input the timezone?
The expectation is that the clients current timezone is used. So if the current local time is before the time change (-06:00), then if I select November 1st 01:30 I expect the timezone to be (-06:00). If the current local time is after the time change (-07:00), then if I select November 1st 01:30 I expect the timezone to be (-07:00).
At the moment the KendoDateTimePicker doesn't match those expectations, and instead defaults to the pre-time change timezone of (-06:00) regardless of what the timezone of the web server or the client is. It is therefore impossible to select time between 01:00:00 - 01:59:59 (-07:00).
Is this a bug or is there someway of making the datetimepicker aware of the client's current timezone?
