It's actually a very hard problem.

To authenticate a time server, one needs to check some sort of
certificate and check the expiration/valid times (or else there is no
means of revocation).

In addition, one needs to be very clear on whether the mechanisms used
to secure the routing infrastructure (e.g. OSPF MD5, IPsec for OSPF,
etc.) need time to function.   This leads to a hierarchy of how the
entire network system is bootstrapped.
