Manually Setting the System Time

Tutorial Steps

This tutorial applies to SecureSync and NetClock 9400. The instructions below are given for the web interface starting in v5.1.2.

The master clock / time server can be synced to several different types of time references.  Besides being able to sync to references such as GPS, it can also sync to other time servers (via NTP for example). You can prioritize multiple references. You can even set the “Local System” as a reference when there is no other reference available. You do this by setting “User 0” as a reference in the Reference Priority table and manually setting the system time. The typical use of this case is when you do not have an accurate external time reference but you want to use the unit as a valid NTP server.

General Notes:

1) System time is considered valid only when Manual Time Set is selected and submitted in the configuration. But this does not maintain the "local time" during power recycle so you can correct for any time offset while then unit was unpowered. However, if you wish to automatically have local time valid after a reboot, then you can configure the "Synchronize to Battery Backed Time on Startup".

2) If there are enabled references higher in the priority table than "User 0", manual time can be set and used until a higher reference becomes valid. The local time will be synced to the reference and there is no longer any validity to the previous manually set time. If the higher reference is lost, the unit will go into holdover and the local time will act as synchronized for the duration specified in the holdover parameters.

To manually sync the NTP time server to the local clock:

  1. First enable the User 0 /User 0 reference in the Reference Priority table (Management -> Reference Priority page of the browser).

    User mode enabled

    Note: If there are any other  higher priority references (such as GPS for example) listed in this table and a higher priority reference becomes present and valid, it will automatically override the manually set time.

  2. Navigate to the Management -> Time Management page of the browser. 
  3. Press the gearbox ICON next to “System Time” in the upper–left corner of the page.
Manually setting the time
  1. Select the “Manual Time Set” box.
  2. If you wish for the time server to go back into sync automatically after each boot-up, enable the "Synchronize to Battery Backed time on Startup" checkbox.
  3. Either change the System Time and Date to the desired UTC time (not local time), or leave it set to the current date/time.
  4. Press the Submit button.
The time server will now be synced to itself and NTP will be declared Stratum 1.
