Ahoj,

můj konfigurák je tento níže. Beru si čas z censetu, ale když je ten jejich ntp nedostupný, tak to vezme lokální čas. Což mi přijde, že je celkem často nedostupný, teda jednou za měsíc.

Případným radám se nebráním. Nastavoval jsem to dle návodů. https://www.google.cz/?gws_rd=ssl#q=linux+ntp+server

# You do need to talk to an NTP server or two (or three).

# pool.ntp.org maps to about 1000 low-stratum NTP servers.  Your server will
# pick a different set every time it starts up.  Please consider joining the

# Note that "restrict" applies to both servers and clients, so a configuration
# that might be intended to block requests from certain clients could also end
# up blocking replies from your own upstream servers.

# By default, exchange time with everybody, but don't allow configuration.

# If you want to listen to time broadcasts on your local subnet, de-comment the
# next lines.  Please do this only if you trust everybody on the network!
