TAI64n

Swift package offering TAI64n label parsing to create a Date object, and a getter property to produce a TAI64n label.

It is implemented as an extension to the Date object

Caveats

• It produces a full nanosecond component in the label which, when parsed will very likely not match the original. Ignoring the last byte of the label should be reliable.
• It is probably slow.
• It uses the new RegexBuilder because it can, and it is probably efficient, but it does mean that MacOS 13, iOS 16, tvOS 16, or WatchOS 9 is required.

Usage

init?(tai64nLabel: String) -> Date?
tai64nlabel: String

Example

let dt = Date(tai64nLabel: "@400000000000000000000000") // 1969-12-31T23:59:50.000
dt?.tai64nlabel // @400000000000000000000000
