hi there,

in "process logs" i see proper time-zone/and the correct time , in the dashboard it shows a different timezone like this :

how to change also in AirWave AWMS the 24hour format so we dont have to calculate the time-format .

ISO8601 i think is the key...

On the AMP side, it's a feature request to submit via Ideas Portal.  Things to double check: System -> Performance -> Current Time, and then Group -> Basic -> Timezone.  As you may place different devices in different groups based on timezone.

Hi ,

>>System -> Performance -> Current Time

shows pacific time America/Los_Angeles

the timezone set in basic is Europe/Berlin

I googled , and found that "tzselect" should work i tried to set :

[root@localhost mercury]# tzselect

The following information has been given:

        Germany

Therefore TZ='Europe/Berlin' will be used.
Local time is now:      Wed Dec  4 09:53:08 CET 2013.
Universal Time is now:  Wed Dec  4 08:53:08 UTC 2013.
Is the above information OK?
1) Yes
2) No
#? 1

You can make this change permanent for yourself by appending the line
        TZ='Europe/Berlin'; export TZ
to the file '.profile' in your home directory; then log out and log in again.

Here is that TZ value again, this time on standard output so that you
can use the /usr/bin/tzselect command in shell scripts:
Europe/Berlin
[root@localhost mercury]# date
Wed Dec  4 00:53:35 PST 2013

************

it still shows 00:53 but now i germany it's 09:53 ,

i then checked here:

[root@localhost mercury]# vi /etc/sysconfig/clock

and changed there ZONE="America/Los_Angeles"

to ZONE="Europe/Berlin"

and did a reboot.. let's see :

still shows wrong :

[root@whde-srv11 mercury]# date
Wed Dec  4 01:04:07 PST 2013
[root@whde-srv11 mercury]#

any further tweaks , we dont mind the am/pm format , it would help if just the german time would appear there

if using this command :

[root@whde-srv11 mercury]# ln -sf /usr/share/zoneinfo/Europe/Berlin /etc/localtime
[root@whde-srv11 mercury]# date
Wed Dec  4 10:07:51 CET 2013
[root@whde-srv11 mercury]#

it shows then the correct time , also in system-performance .. also in the client-tab , that would help . let's see if it works after rebooting ;-)

Ok this seems to work , if you "restart amp" then an error will occur, i had to completely reboot the AMP and now the correct time is still there.

so is this some valid workaround?

summarized , i only did this now :

root@whde-srv11 mercury]# ln -sf /usr/share/zoneinfo/Europe/Berlin /etc/localtime
[root@whde-srv11 mercury]# date
Wed Dec  4 10:07:51 CET 2013
[root@whde-srv11 mercury]#

and here's still Europe/Berlin ... so this stays also after reboot :

[root@whde-srv11 mercury]# cat /etc/sysconfig/clock
ZONE="Europe/Berlin"
[root@whde-srv11 mercury]#

Word of caution: AirWave is very sensitive to time changes (as all data is referenced to a locale time stamp or epoch value).

With that in mind, instead of using TZselect, I usually refer users to re-use the time setup that occurs during initial system install:

# /root/svn/mercury/install/time-setup

Data in the database and RRDs are using epoch time values while most logs use locale time stamps, so be very careful not to make a mistake and put yourself into the future.  It's okay if you put yourself in the past, the visible side effect of moving backwards in time is that no new data will be recorded until it passes that last recorded update in the RRD.  So if time was moved back an hour, new data would not be seen until the system time passes the last recorded data point.  But if by accident the time is set a year in the future and then set back to current time, the RRDs will have updates to that future time and won't record new data until that time is passed.  The solution there is to either blow away all RRD data and start from scratch, or restore the last backed up data from a nightly backup.
