Time stamp of last boot

I have been trying to determine the best way to get a full timestamp for the last time of system startup (in Terminal.)

I pulled the timestamp from

“ls -1lnUT /var/run/utmpx”

Is there a better method, or, is there a situation where this method would not work?

Thank you in advance.

who -b

Your example appears to report the same time:

iMac06:~ john$ who -b

reboot ~ Sep 2 15:49

iMac06:~ john$ ls -1lnUT /var/run/utmpx

-rw-r--r--@ 1 0 1 4396 Sep 2 15:49:34 2017 /var/run/utmpx

iMac06:~ john$
