-## Nim OID support. An OID is a global ID that consists of a timestamp,
-## a unique counter and a random value. This combination should suffice to
-## produce a globally distributed unique ID. This implementation was extracted
-## from the Mongodb interface and it thus binary compatible with a Mongo OID.
-##
-## This implementation calls ``math.randomize()`` for the first call of
-## ``genOid``.
