Hello everyone,
I wanted to know what the ramifications of syncing a Primary and Backup gateway to a NTP source would be if the NTP time is about 10 minutes behind the current time of the primary and backup.
E.G. the NTP time is currently 1:50PM and the time on the gateways is 2:00PM.
I assume the database will find primary key conflicts with some of the inserts but are there other issues I need to look out for before syncing up the gateways?
Thanks.
What kind of server OS?
If Linux, you can make it slew to the correct time instead of jumping.
I was thinking about that.
It is Windows but we are using a tool called Meingburg to act as the NTP client/server instead of the built-in Windows NTP
No clue.
oops. misspelled it: Meinburg
I'm going to see if I can make it do slow updates instead of a big jump as you suggested.
In Linux, the slewing is done by changing the kernel's clock constant so "realtime" runs faster or slower at the microseconds level--no discontinuities. If Meinburg can do that with Windows, that would be good to know. If it cannot, then even second by second jumps will produce conflicts.
