who -b shows different output format on Mac and Linux

I am trying to find a way to get output format of who -b same as in linux but on OSX i get format as below. MAC

% locale | grep LC_TIME
LC_TIME="en_US.UTF-8"
% who -b
reboot   ~        Nov  4 08:52

LINUX

[root@jump-host1 ~]# who -b
         system boot  2020-10-28 07:53
[root@jump-host1 ~]#

LOCALE is same on both linux and mac. How to get same format as linux on mac output of who -b Also i found these properties are getting inherited when i do ssh to linux host is what i understood but when i run who -b as root i get the above output from linux. **OSX**

bash-3.2$ alias who;type who;ldd $(type -p who) 
bash: alias: who: not found
who is /usr/bin/who
bash: ldd: command not found
bash-3.2$

**LINUX**

[jump-host1 ~]$ alias who;type who;ldd $(type -p who) 
-bash: alias: who: not found
who is /usr/bin/who
