if you have a date set before 1970 you can't make any network connects to anything. You can still connect to the box and make dns lookups. However you can't even ping 127.0.0.1 it sends no packets

change the date to any after 1969

 I ran into this. It's not an issue with the networking stack, but with ping
 (or, rather, a time-related function in ping). 
 It's probably safe to say that running with a date before 1970 isn't supported
 (and the system should reset the date to Jan, 1 1970 if it finds such a
 date at boot).

 As of September, 2006, port-cobalt (and just about everybody else)
 was converted to use the new TODR code.  This code has sanity checks
 on initialization to ensure that the time of day is reasonable on
 boot.  Currently it checks for:

 Filesystem time > 5 * SECYR
 Realtime clock > 25 * SECYR

 The code ensures that the date is beyond 1970, which should allow
 ping to function.  Note that many other programs may fail on negative
 date values along with ping, this also helps them.
