An alias is a keyword that is substituted for a command. Usually, an alias is used for a longer, complicated, or hard to remember command.
There are many aliases that display the current time from around the world. In most cases, it's name of a main city - paris, london, vancouver, tokyo. There are some that have names for the time zone they represent - utc, gmt, eastern, central, mountain, and pacific.
$ utc
Mon Mar 25 21:17:13 UTC 2019 -- Universal Time
In addition to these, I've added some aliases that group some clocks by the continents.

PARSE_GIT_BRANCH: detects when you're in a git project and extracts the name of the active branch. Used by the set_prompt() function
$ parse_git_branch
PREAMBLE: Display a login message about who and where you are.
$ preamble
PROMPT: A great way to display a line to text. Like echo, but types out the characters one at a time, as if you typed it
PUNCH: keep track of when you start and stop working on things by writing to the timesheet.txt file. the included timecalc.php scripts parses the timesheet.txt file. Great for freelancers who track their time, and use tools like GetHarvest or Free Agent.
It's first argument can be 'in', 'out', 'note', or 'switch'. The second argument is only required for 'note', but it's useful for keeping track of what you work on
$ punch in
$ punch in "type a brief message here"
$ punch out
$ punch out "type a brief message here"
$ punch note "type a brief message here"
$ punch switch "type a brief message here"
For best results, add a note when you punch in. Include things like an issue number, client name, or project name and a few words about the task. I'd love to know what works for you.
SET_PROMPT: Allows you to easily change the values displayed in your prompt. Uses the parse_git_branch() function.
