Adding timestamp to each line on Zsh

I just fresh installed Sierra and wanted to use zsh with oh-my-zsh and power shell...

I ended up with a terminal like this:

But I want to add a timestamp to every output. Semething linke:

[14:23] acytryn ~ Projects %

Is there a way to do this with zsh?

If you prefer the 24-hour format, use this

PROMPT='%{$fg[yellow]%}[%D{%y/%m/%f} %D{%K:%M:%S}] '$PROMPT

diff is '%L' to 'K'

I've found it more non-destructive to actually prepend the time to the existing prompt without overriding it completely. This makes it work with any existing theme without interfering with its styling.

Add this at the end of your .zshrc file. You can type the command nano ~/.zshrc to edit it using nano:

PROMPT='%{$fg[yellow]%}[%D{%f/%m/%y} %D{%L:%M:%S}] '$PROMPT

I use cloud theme, so this gives me:

It retains the current theme. You can also add some styling to the timestamp, by changing the color, or even the format. You may refer to the official Zsh Date and Time formatting linked here: https://zsh.sourceforge.io/Doc/Release/Prompt-Expansion.html#Date-and-time. This uses Linux's strftime3 (https://man7.org/linux/man-pages/man3/strftime.3.html) to format the Date (%D) string.

Make sure to reload your .zshrc file by typing:

. ~/.zshrc

source ~/.zshrc

PROMPT='%F{219}[%D{%d/%m/%y %H:%M:%S}]%f '$PROMPT

Thanks to @wcyn for his great answer. I made it more readable by:

Removing the second D
Changing the hours format to 24-hour format: from L to H
Changing the day format to 2 digits: from f to d
Changing the coloring format

Explanation

To color text, use this syntax:

%F{color_code}My_Text%f

Specifically, color code 219 sets a light purple color. You can discover the color encodings with this awesome answer

Yes. Just open your ~/.zshrc and add this line at the end of it (using nano ~/.zshrc command in terminal, for example):

PROMPT='%{$fg[yellow]%}[%*] '$PROMPT

And you'll get it like this:

You can change [%*] section to get other formats:

 %D     The date in yy-mm-dd format.
 %T     Current time of day, in 24-hour format.
 %t %@  Current time of day, in 12-hour, am/pm format.
 %*     Current time of day in 24-hour format, with seconds.
 %w     The date in day-dd format.
 %W     The date in mm/dd/yy format.
