We are running openLDAP 2.4.39 in an MMR replication on Ubuntu 14.04. I have one node that is not wanting to sync with other nodes giving the following error:

As you can see the CSN shows the exact same time the time that is being logged. We are in the U.S. Central timezone. I have checked our ntp service on my three nodes. All three are pointed to the same ntp and are in sync. Would be possible that one node might still be just a few miliseconds too fast and the csn timestamp would appear wrong? Is there a logging level I can set for that specific issue? I am currently logging the sync records. I can go to debug in needed.
a) Please don't resend your emails to the list. The first one got through fine, which you could easily verify by looking at the list archives.
b) Not enough information provided here to go on. Are all server IDs unique? Are all syncrepl clauses unique per DB? Personally I've never found ntpd particularly good at keeping clocks in sync. I've generally resorted to running ntpdate frequently out of cron, particularly for VMs.
