Set Time zone in OSX to UTC

OSX UTC Time Zone

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

I verified that selecting UTC - United Kingdom in the Date & Time panel on macOS 10.14.6 really does set it to UTC and not to UK time, which could be UTC+1 during daylight savings.

Hi all! I am having issues with meeting invites from my client in Dubai and I live in UK. While the invite says 4PM AST (Arabian Standard Time) is shows up at 2PM UK time, but should be 1PM UK time. Any fix you can suggest?

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

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'
