Generate a version 1 UUID from a host ID, sequence number, and the current time and shorten it.

@param int|string $node A 48-bit number representing the hardware address
This number may be represented as an integer or a hexadecimal string.
@param int $clockSeq A 14-bit number used to help avoid duplicates that
could arise when the clock is set backwards in time or if the node ID
changes.

@return string
Generate a version 1 UUID from a host ID sequence number and the current time and shorten it .
