I don't know how exactly it comes but I guess it has something to do with
local vs. system time. You have UTC as timezone but because of DST it's
one hour apart.
What does last report?
On my test system I find the reboot which is shown in the who -b output in
the last output, and the uptime reported by last again matches with the
uptime output.

Simon
