The OSF DCE Rationale talks about services inside a cell and between
cells.  A cell is a group of 2-1000 well-connected hosts, basically
all the "local" machines.  Services inside a cell are optmised for
performance, availability, and management.  Services between cells are
optimised for interoperablity and scalability (10,000 cells), and tend
to be International Standard kind of things.

A good example is name service: DECdns inside a cell, X.500 between
cells.  DECdts adds replicated servers, caching, and some other stuff
that X.500 doesn't do.

For time service, the "between cells" part of the DCE is left blank.
I don't really think that OSF expects DECdts to be the answer for
syncronising 10,000 cells.  NTP could be the answer.
