Even though ntpd service was configured and running, the compute nodes were not using the ntp server as a adjust time server.   Date was being synchronized with the local host address instead.  For example:
ntpq -pn shows is not considered as ntp server:
[root@odm3db01 ~]# ntpq -pn
remote           refid      st t when poll reach   delay   offset  jitter
==============================================================================  .LOCL.           1 u  235 1024  377    0.450  44675.7 540.772  .À¨Q—.          16 u  915 1024    0    0.407  29730.3   0.000
*     .LOCL.          10 l    5   64  377    0.000    0.000   0.001
ntpdate -q showed as a "step time server"  instead off "adjust time server"
#ntpdate -q
server, stratum 1, offset 44.789175, delay 0.02589
10 Aug 13:45:39 ntpdate[31711]: step time server offset 44.789175 sec
