They "should" synch when they talk to the CAS. If this is not happening, then I suggest you open a ticket.
If it is so that a brand new AMD has come online, the adjustment takes place in small steps for every time the CAS and AMD talk.
As the link Raff is pointing to, it eludes to this "If the AMD is not managed by a report server," but I guess yours is?
Yep, if the AMD is not managed by a report server, Shashi please check the AMD General options config:
Check the IP address of the server authorized to set AMD time is the IP address of the main reporting server (usually the primary CAS).
Hope that helps.
Before that i just want to let you know is in fact the probes which are not synchronized are not AMD one's instead Synthetic one and other probe one.
And also I tried to access the file /etc/ntp.conf but I didnot find neither in CAS nor AMD config folder, i am not sure where this files resides.?
To start with , the AMD ALWAYS has the NTP.CONF file in the ETC directory. If you don't have that, something is wrong as this is a default component of every *NIX installation.
In Windows, you usually have to either get some third party or Open Source tool as I "Think" the default time mechanism in Windows isn't based on NTP (at least it wasn't before).
But if you go and ask the Network team in your Company, I bet they already have a Time Server somewhere. Use that one for all your machinery. If all your machine synch against that, you will not have any problems, even if their time might not be perfect, but it'll be the same 🙂
