Configuring SNTP Servers in Windows terminal

w32tm /config /syncfromflags:manual /manualpeerlist:"time.cloudflare.com nts.netnod.se time.mikes.fi 0.pool.ntp.org 1.pool.ntp.org 2.pool.ntp.org 3.pool.ntp.org"
w32tm /resync
w32tm /query /peers
  • The list is space separated NTP servers, while I think Windows uses SNTP instead of NTP.
  • /resync may sync current time, but is also required for the GUI (Windows + I, Date & time) and following command to get aware of peers.
  • Shows where time is synced from and statistics.
    • There is also net time to sync, I am unsure of the differences while that may be blocked while the second keeps working. It may also not show all the peers, just the primary one, while w32tm is more verbose and has all of them.

Variations

Variations of the timeserver setting command to be kept at hand

Note: time.cloudflare.com and nts.netnod.se probably work everywhere and I am keeping the second at hand in hopes of Windows implementing support for NTS. Additionally Sweden is a neighbouring country and thus doesnt seem too bad location for an NTP server.

Finnish WISP that I seem to often be a customer of.

w32tm /config /syncfromflags:manual /manualpeerlist:"time.cloudflare.com nts.netnod.se ntp1.kolumbus.fi ntp2.kolumbus.fi ntp.saunalahti.fi time.mikes.fi pool.ntp.org"
