registry.xml ntp server issue #102

Closed sebenste closed 2 years ago

sebenste commented 2 years ago

LDM 6.13.16 has a list of several NTP servers it uses to verify the accuracy of the system clock. Unless this has recently changed, nearly all of those servers are dead, having been added years ago. I would like for the LDM to default new installations to point to to us.pool.ntp.org for an NTP time check by default. This has at least four benefits:

  1. It defaults to a server pool that has been around for a long time, and from all indications, it should not be going away anytime soon.

  2. A new install I did from scratch had all servers fail (only one or two actually work in the list). This causes a slow start to the LDM, and we know what happens if the system clock is off;

  3. Currently, us.pool.ntp.org has 825 servers to ping off of. Thus, when some are out of service, there are many more to pick up the slack.

  4. If a server drops out, no worries. There are 800+ more to choose from!

And of course, it causes the LDM to start up as quickly as possible.

Done. It'll be in the next release.
