Start

Definition of the start time at which the display should begin.

Several options are available as values:

The keyword First: The first available value is used as the start value of the display.
An ISO8601 timespan such as PT1H1M (one hour and one minute). The corresponding specification is: P[JY][MM][WW][TD][T[hH][mM][s[.f]S]]. Values that are not set (e.g. year) do not have to be entered. Example: PT1M0.5S refers to one minute and half a second. This timespan describes the "distance" at the End time of the control. Therefore only one of the two attributes should be configured with a timespan.
An ISO8601 time. Please note that the time must be specified in UTC. In the control itself the time is displayed in the time zone of the current user and can be manipulated. On a system with the time zone Europe/Berlin 2019-08-21T11:35:21.576 is displayed, for example, but the control uses the UTC specification 2019-08-21T09:35:21.576Z (the letter Z indicates this).
