Issue Description
The alarms displayed in the N2000BMS are displayed with an early hour.
The alarm is reported in the OLT  MA5600V800R007


the next alarm is reported in the OLT at 01:39:49-05:00, but, in the N2000BMS appear the same alarm at 02:39:49. The time in the N2000BMS is the real time.

Alarm Information
Handling Process
Becasue of the BMS had the correct time, so, it was supposed that the DST was not configured in the NEs.

it was analized the time settings and the tme zone  in the OLT.

Ceylan(config)#display time                                                    
{ <cr>|dst<K>|time-stamp<K> }:                                                 

          display time                                                         
  2011-11-02 10:10:03-05:00                                                                                                                                   

Ceylan(config)#display timezone                                                
The current time zone:  GMT-05:00

it was found that the timezone is not the correct. so it was requested change the timezone to make a test.

{ GMT<E><GMT+,GMT-> }:GMT-                                                      
{ time<hh:mm><S><Length 3-5> }:6:00  

after modify the time zone to the correct one, the alarms was reported in the N2000BMS with the correct time.
however, to avoid changing the timezone every period of time, it was suggested to enable the DST.

Ceylan(config)#display time dst                                                
  Failure: DST has not been configured  


Root Cause
verify the timezone of the country to set the correct one in the NE or in the Server.
also, consider use the DST feature.
