FYI:

I recently came across a large military network that has an interesting
approach to maintaining network time: Each switching center has a Loran-C
receiver from which they derive time and clocking. Since the Loran system
maintains a very accurate clock (it's intrinsic to proper operation), this
all seems to work.
