``snowflakeid(Representation,EpochMilliseconds,TimeUnitMilliseconds,TimestampBits,NodeBits,SequenceBits,Node)``
===============================================================================================================

* ``Representation`` - Snowflake ID representation. Possible values are ``integer``, ``atom``, ``chars``, and ``codes``.
* ``EpochMilliseconds`` - Custom epoch in Unix milliseconds.
* ``TimeUnitMilliseconds`` - Timestamp unit in milliseconds.
* ``TimestampBits`` - Number of timestamp bits.
* ``NodeBits`` - Number of node bits.
* ``SequenceBits`` - Number of sequence bits.
* ``Node`` - Node identifier value.
