How is system time set? Is ntpdate run after the network is ready?
How long does it retry waiting for the network to be available?
Recent Fedora versions have switched from ntp to chronyd. chronyd is
built for the laptop/tablet era where networks can come and go, and will
slam in a time as soon as it sees a network instead of waiting for the
clock to get stable.
Ah, that is how it is done in Fedora. I wondered that.
But that still does not help when the network is not available.
I have seen a number of challenges becuase the system time is bac at
the epoch start as there is no battery rtc. And I wonder how many
armv7 boards have a battery to maintain time across boots?
I bought a battery for my board, and yes this is a problem for ARM
boards, but I've also seen this issue on old Intel systems where the
BIOS battery has died.
