[ale] NTP/Chrony time zone persistence

[Jeremy T. Bouse]

I know older versions of SUSE on ESX 5.x have issues with time sync and
I believe it's kernel related as I recall.

We've got RHEL and CentOS < 7 (5 & 6) running in ESX 5.x without this
type of time issue.

Another thing to consider is the actually BIOS and ESX time/timezone
settings. Is the BIOS in UTC or localtime? Same with the ESX server
itself. Does this differ from the CentOS guest VM? It could be that the
systems don't match in what they believe the hwclock time is set to and
are treating it incorrectly on startup when the OS will look at the
hwclock to get the initial time and set it.
