ranged-date

MIGRATION NOTICE:

• ranged-date 2.0.0: back and forward ranges are now mandatory (were 0.5 each by default in 1.x.x).
• ranged-date 2.0.0: Date Objects with values outside of the specified range will return false (would return Date Object in 1.x.x).

Converts a given string, number, or Date object to the number of milliseconds since the Unix epoch, provided that it can be recognized as millisecond, second, or microsecond time within a specified range from the current date.

Milliseconds, seconds, or microseconds may be excluded as possibilities for range matching.

Useful for:

• Parsing timestampted data from external APIs.
• Integrating collections containing mixed timestamp formats.

rangedDate(new Date().toString(), 1, 1)
rangedDate(String(Date.now()), 1, 1)

// All return false
rangedDate(Date.now() - 10000000, 0.0000001, 0.0000001)
rangedDate(Date.now(), 1, 1, {ms: true})
