Intervals Formatters

Updated on Mar 26, 2026

Every RadTimeBar's interval has a preset collection of formatting strings that creates the string representation of a given date to match the interval. RadTimeBar automatically chooses the appropriate string formatter according to the control size and visible range.

The table shows the available formatters per Interval:
