Linux uptime command looks at file /proc/uptime and last reboot shows the reboot entry from /var/log/wtmp. The reboot entry is placed (I suppose) by init command and /proc/uptime shows uptime from the kernel's point of view - from starting the 1st CPU. Nobody knows your system better then you, but I would trust the output of uptime. wtmp file is easy to manipulate and it starts on the same date, as it shows last reboot. It may be, that last doesn't find any reboot entries at all and just reports the first entry of the file as last reboot time.
