Seems there's no ntpd in centos7, how can I sync time in centos7?
I found out that chrony
should be used in centos7, what is manual way to update time using chrony?
I assume chronyd is something equivalent to ntpd? and what's the command equivalent to ntpdate -s time.nist.gov
?

Unless you've changed chrony's configuration, you don't need to do anything but start the service.
The default configuration automatically steps the clock at startup (using the
makestep
directive) if it is more than one second different than the default NTP servers.If you explicitly removed
makestep
from the configuration, you can step the clock by using the commandYou should NOT do this if you used the non-default
rtcfile
option though, as it will cause the RTC drift to be recorded incorrectly.For further details see the RHEL 7 chrony documentation.
