Pages 62-63 of the VNX System Operations document (http://corpusweb130.emc.com/upd_prod_VNX/UPDFinalPDF/jp/System_Operations.pdf) covers setting the timezones.  However it doesn't seem to work trying to assign "UTC" or "Etc/UTC" as the zone to use.

I was reviewing the hidden .ckpt directory for one of our NFS mounts to look at the checkpoints and noticed the VNX is using the zone name in the name of the checkpoint directories:

# ls -l .ckpt

total 192

Here is the results of trying to set the first data mover to use UTC by specifying both POSIX names and Linux names for the zone (referring also to pages 28-29 of https://mydocs.emc.com/VNXDocs/TimeServices.pdf):

[nasadmin@vnx ~]$ server_date server_2

server_2 : Fri Aug  9 14:45:27 EDT 2013

[nasadmin@vnx~]$ server_date server_2 timezone -name Etc/UTC

server_2 :

Error 10279: server_2 : Invalid time zone: Etc/UTC.

[nasadmin@vnx ~]$ server_date server_2 timezone -name UTC

server_2 :

Error 10279: server_2 : Invalid time zone: UTC.

[nasadmin@vnx ~]$ server_date server_2 timezone UTC

server_2 :

Error 13157400579: server_2 : Invalid argument(s).

[nasadmin@vnx ~]$ server_date server_2

server_2 : Fri Aug  9 14:45:56 EDT 2013

Is it not possible to set the Data Mover to use UTC?  Do I need to use GMT instead?  We have all our servers and network equipment set to use UTC and would like to have the VNX use UTC as well to make time alignments easier to figure out when looking at logs.
