This is all I can find re time; Help it helps.
The contents of the time stamp differ depending on whether you have set the time and date on the onboard system clock:
• If you have set the time and date on the onboard system clock, the date and time are shown in the following format:
mm dd hh:mm:ss
• mm – abbreviation for the name of the month
• dd – day
• hh – hours
• mm – minutes
• ss – seconds
For example, “Oct 15 17:38:03” means October 15 at 5:38 PM and 3 seconds.
• If you have not set the time and date on the onboard system clock, the time stamp shows the amount of time that has passed since the device was booted, in the following format:
• <num>d – day
• <num>h – hours
• <num>m – minutes
• <num>s – seconds
For example, “188d1h01m00s” means the device had been running for 188 days, 11 hours, one minute, and zero seconds when the Syslog entry with this time stamp was generated.
Synchronizing time - NTP
After the system peer is chosen, the system time is synchronized using one of the following ways based on the time difference with system peer:
< 128 msec - The system clock is adjusted slowly towards the system peer time reference time.
> 128 msec and < 1000 sec - The system clock is stepped to the system peer reference time and the NTP state information is cleared.
> 1000 sec - NTP is operationally disabled. The admin should set the time to the current UTC time.

You can also check the precisiom of the NTP using the show ntp status command
Displaying NTP status
Use the show ntp status command to display the NTP status
