Exact time in the FI network
A server can be used to synchronize the exact time of computers
time.fi.muni.cz . The server provides the exact time log
NTP (or
SNTP ) from anywhere on the Internet and protocol
time (RFC 868) within the FI network.
This server is part of a distributed network of NTP servers NTP Pool Project , see also monitoring graphs for IPv4 and for IPv6 .
You can also read something about our practical experience with NTP operation in the article Accurate time and network transparency our blog.
Unix time synchronization
For accurate synchronization, you need to install the NTP daemon (typically the
ntp , No
openntpd ). In the configuration file
/etc/ntp.conf then we recommend setting up a faculty NTP server, ie adding a line
server time.fi.muni.cz iburst and comment on lines with directives
pool .
The alternative is
chrony (
chronyd ). If you are a server
time.fi.muni.cz have not already been set during installation, this can be done by commenting out the line with the directive
pool in the file
/etc/chrony.conf and adding a line
server time.fi.muni.cz iburst .
Time synchronization on Windows
In Windows, the command can be used
w32tm /config /manualpeerlist:time.fi.muni.cz /syncfromflags:manual /update
which must be run on the command line with administrator rights.
To check the settings, use
w32tm /query /configuration
