Here is how to set the clock in your Airwave server, both system clock and hardware clock. It HAS to be accomplished in CLI.
This was done in Airwave 8.2.0.3
1. How to check your time:
[root@Airwave mercury]# clock
Wed 15 Jun 2016 09:45:23 AM EDT -0.500183 seconds
2.Setting the clock and timezone setings:
[root@Airwave mercury]# cd /root/svn/mercury/install
[root@Airwave install]# ./time-setup
------------------------ Date and Time Configuration ---------------------
Current Time: Wed Jun 15 09:46:31 EDT 2016
1) Change Date and Time
2) Change Time Zone
0) Finish
* I have found that the timezone need to be set before setting the time as it adjusts the time if done second.
3. Check hardware clock:
[root@Airwave install]# hwclock
Wed 15 Jun 2016 09:47:27 AM EDT -0.062704 seconds
4. Sync the clocks (system and hardware):
[root@Airwave install]# hwclock --systohc
