The exact time in the FI network

The time.fi.muni.cz server can be used to synchronize the exact time of computers. The server provides accurate log time NTP anywhere from the Internet and the protocol time (RFC 868) within the FI network.

Synchronize time on Unix

For exact synchronization, you need to run the NTP daemon in client mode (typically a package ntp , No openntpd ), for example, with the following configuration file ntp.conf :

restrict default nomodify notrap noquery
restrict 127.0.0.1
server time.fi.muni.cz
driftfile /var/lib/ntp/drift

or simply add an existing configuration file server time.fi.muni.cz .

An alternative is the chronyd, which is part of some distributions (such as Fedora). If you are a server time.fi.muni.cz (= pyrrha.fi.muni.cz ) have not already set up during installation, this can be done by stating the "pool 2.fedora.pool.ntp.org iburst" line in the file /etc/chrony.conf and add a line:

server time.fi.muni.cz iburst

Synchronize time on Windows

You can use the command in Windows

w32tm /config /manualpeerlist:time.fi.muni.cz /syncfromflags:manual /update

Note: you need to run on the command line with admin rights

Use the

w32tm /query /configuration
