isValidTimeRange

Signature

isValidTimeRange(props: { value1: string; value2: string; options?: { allowEqual?: boolean; }; }): boolean

Return true if value1 and value2 form a valid time range — both parseable as ISO PlainTime strings and value1 before value2.

• Both inputs must be ISO 8601 time strings (e.g. "14:30:00"), as isValidTime accepts, annotations included.
• Ordered by Temporal.PlainTime.compare, to the nanosecond.
• Invalid input, malformed strings, or leap-second strings return false.

Options

props

The two values to compare and how equal values are treated

Option	Type	Default	Description
value1	string	Required	The start of the range, an ISO PlainTime string.
value2	string	Required	The end of the range, an ISO PlainTime string.
options?	object	None. Equal values are not a valid range.	The settings for the comparison. It must be an object or omitted; any other value, null included, returns false.
options.allowEqual?	boolean	false	Whether value1 equal to value2 is a valid range. false requires value1 to be before value2.

Returns

boolean indicating whether the time range is valid
