Set Time zone in OSX to UTC

OSX UTC Time Zone

sudo ln -sf /usr/share/zoneinfo/UTC /etc/localtime

works on MacOs Mojave thanks !
any tip to revert this (in case i need to in the future)

Command To See What Your Local Time Is Currently Set To:

[$]> ls -la /etc/localtime

/etc/localtime -> /var/db/timezone/zoneinfo/America/Los_Angeles

Command To Set Your Local Time To UTC

[$]> sudo ln -sf /usr/share/zoneinfo/UTC /etc/localtime

NOTE: When I Set It To UTC - United Kingdom Via System Preferences It Becomes:

[$]> ls -la /etc/localtime

/etc/localtime -> /var/db/timezone/zoneinfo/UTC

Command To Switch Your Local Time Back To The Original Time Zone

[$]> sudo ln -sf /var/db/timezone/zoneinfo/America/Los_Angeles /etc/localtime

FYI: I Compared Both Of The UTC Files And They Are Exactly Matching

[$]> delta /usr/share/zoneinfo/UTC /var/db/timezone/zoneinfo/UTC
or
[$]> diff /usr/share/zoneinfo/UTC /var/db/timezone/zoneinfo/UTC

[$]> cat /usr/share/zoneinfo/UTC /var/db/timezone/zoneinfo/UTC

TZif2UTCTZif2UTC
UTC0
TZif2UTCTZif2UTC
UTC0

I created the following shell aliases to make switching timezones easy.

# output the current timezone
alias timezone.current='exa -l /etc/localtime'

# set the timezone to my default local timezone
alias timezone.default='sudo ln -sf /var/db/timezone/zoneinfo/America/Los_Angeles /etc/localtime'

# set the timezone to utc
alias timezone.utc='sudo ln -sf /var/db/timezone/zoneinfo/UTC /etc/localtime'
