I converted physical machine to virtual one, where there is NTPd service.
My 
ESX host is running several guest OS included this NTP server.
Can it be this 
one the problem ? Virtualization ? I'd like to know if ntpd adjusts only OS 
time or it adjust hardware clock too.
In latter case if it adjusted hardwrae 
clock it shuld modify hardware clock directly on ESX server (where there are 
running 0 virtual machine)  ?!

You reference ESX 
host or guest OS ?
Guest OS (where ntpd is running) does other jobs
ESX host 
has 20 runningl virtual machines.
