Title:
  Wrong system clock causes CA client to spin

Status in EPICS Base:
  Invalid

Bug description:
  Using EPICS 7.0.2 on a Linux box with a system clock that was set to
  the Posix epoch (NULL) by an irresponsible time synchronization
  daemon, use of a simple CA client sends it into a fast infinite loop
  printing errors:
