I don't know that it matters too much between MHOs and SGMs, but it might matter between MHOs. It certainly does in R82 because the MHOs set up trust between themselves with certificates, so if the time is wildly out their self-generated certs won't be valid between each other. For whatever reason, MHOs out of the box have their clocks set wildly back and need to be manually set before NTP can take over to manage. Always good to check the time zone too, it defaults to New York and is commonly not changed, and NTP doesn't set the time zone.

MHO time won't affect SMO/SMS comms, the SGMs handle time by themselves, and are generally pretty good out of the box. That said, SIC required time to be pretty close, as Lesley has explained, so NTP is always a good idea for any CP device.
