This section shows how to configure time synchronization settings for the MRU. Users can configure parameters such as NTP synchronization state, server list, and PPS-related settings including ZDA offset, polarity, and decoding options.

Example usage
MRU – NTP Setup & Commands
1. Stop / Start NTP
set,timesync,ntp,state,stop
# Stop NTP timesync
set,timesync,ntp,state,start
# Start NTP timesync
2. Configure NTP Servers
Set full server list (servers separated by ;):
set,timesync,ntp,serverlist,0.pool.ntp.org;1.pool.ntp.org;2.pool.ntp.org;3.pool.ntp.org;10.0.0.100
# Update NTP server list
3. Verify Configured Servers
get,timesync,ntp,serverlist,configfile
# Show servers from config file
4. Check Sync State
get,timesync,ntp,state
# Show current sync status (which server is used)
5. Check Connection
get,timesync,ntp,serverlist,connection
# Show current NTP connection and active time source
