Comment 10 for bug 1372501

I replicated by using provided table definitions, trigger and my.cnf. I tried with 3 node cluster and all machines running NTP and time is synchronized on all nodes. I noticed stamp value for TIMESTAMP column inserted properly on my test case on all nodes of the cluster.

We would need repeatable test case to try to reproduce it.
