Esxi5 time zone problem

hi
i just realized that this esxi 5 server has time problem

its automatically taking utc and its 1 hr different then current time ..

from Configuraiton->time->
correct server address and ntp is running.. but still it has the wrong time ..
and after I turn on the ntp client  on the esxi5 server there is a yellow sign in server name ..

please have a look at picture

how can i change the time to current british time ??

what is the time zone on the Client?

because vSphere translates the time to that of the client.

login to the server and check time

check alerts on the host what is the alarm, it is unlikely to be time!

yes, Red usually means, it's not Syncing or getting a time!

should be Black

Stop NTP, Change time on HOST, to roughly correct time, and then start NTP.

thats odd
chaning date from Vshpere client  does not effect on server

let me try from command line

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
you need to check ntp server, first with software.....

make sure firewalls ports are open, check logs

ntp server is not blocked?

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
if this is ESXi 5.0 phantom alarms, which is a bug.

if no alarms are present in the alarms, or Summary page.

e.g. if you enable ssh you get a warning!

to my knowlegde NTP does not give a warning or alert other than state stopped, started or appear in RED.

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
also HA failover, HA lack of datastores, gives a warning in Summary Page, but is not listed as an alarm.

Check Events, Tasks, Alarm, Summary page for host.

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
red hearing.......!!!

its damn annoying that Warnings now trigger Yellow Triangles, and its not listed in Alarms!

because technically its not an alarm, so VMware state, its a Warning!

I have an article to surpress....l.
