calculateTime

Uses the provided seconds and micro-seconds to calculate the count of 100-nanosecond intervals since UTC 00:00:00.00, 15 October 1582, for RFC 4122 variant UUIDs

public calculateTime(string $seconds, string $microseconds): \Ramsey\Uuid\Type\Hexadecimal

Parameters:

Parameter	Type	Description
$seconds	string	A string representation of the number of seconds since the Unix epoch for the time to calculate
$microseconds	string	A string representation of the micro-seconds associated with the time to calculate

Return Value:

The full UUID timestamp as a Hexadecimal value

---

convertTime

Converts a timestamp extracted from a UUID to a Unix timestamp

public convertTime(\Ramsey\Uuid\Type\Hexadecimal $uuidTimestamp): \Ramsey\Uuid\Type\Time

Parameters:

Parameter	Type	Description
$uuidTimestamp	\Ramsey\Uuid\Type\Hexadecimal	A hexadecimal representation of a UUID timestamp; a UUID timestamp is a count of 100-nanosecond intervals since UTC 00:00:00.00, 15 October 1582.

Return Value:

An instance of {@see \Ramsey\Uuid\Type\Time}
