StepMode
public enum StepMode : String, Encodable
Sets the range update mode.
If backward, the range update shifts the start of range back count times step
milliseconds. If todate, the range update shifts the start of range back to the first
timestamp from count times step milliseconds back. For example, with step
set to year
and count
set to 1 the range update shifts the start of the range back to January 01 of the
current year. Month and year todate are currently available only for the built-in (Gregorian)
calendar.
