-Our team is spread across the world, from the USA all the way to Australia, so having some sort of world clock makes sense.
-Currently, I am using an extension for Gnome called [Timezone extension](https://extensions.gnome.org/extension/2657/timezones-extension/), and it serves the purpose quite well.
-But I also have a bunch of electronics that I bought through the time, and I am not using any of them, and it's time to stop hording this stuff and use it in a project.
-A while ago I bought a small eInk display [Inky pHAT](https://shop.pimoroni.com/products/inky-phat?variant=12549254217811) and I have a bunch of [Raspberry Pi's Zero](https://www.raspberrypi.org/products/raspberry-pi-zero/) lying around that I really need to use.

-Since the Inky [Inky pHAT](https://shop.pimoroni.com/products/inky-phat?variant=12549254217811) is essentially a HAT, it can easily be added on top of the [Raspberry Pi Zero](https://www.raspberrypi.org/products/raspberry-pi-zero/).
-First, I installed the necessary software on Raspberry Pi with `pip3 install inky`.
-And then I created a file `clock.py` in home directory `/home/pi`.
-```python
-#!/usr/bin/env python
-# -*- coding: utf-8 -*-
-import sys
-import os
-from inky.auto import auto
-from PIL import Image, ImageFont, ImageDraw
-from font_fredoka_one import FredokaOne
-clocks = [
-  'America/New_York',
-  'Europe/Ljubljana',
-  'Australia/Brisbane',
-]
-board = auto()
-board.set_border(board.WHITE)
-board.rotation = 90
-img = Image.new('P', (board.WIDTH, board.HEIGHT))
-draw = ImageDraw.Draw(img)
-big_font = ImageFont.truetype(FredokaOne, 18)
-small_font = ImageFont.truetype(FredokaOne, 13)
-x = board.WIDTH / 3
-y = board.HEIGHT / 3
-idx = 1
-for clock in clocks:
-  ctime = os.popen('TZ="{}" date +"%a,%H:%M"'.format(clock))
-  ctime = ctime.read().strip().split(',')
-  city = clock.split('/')[1].replace('_', ' ')
-  draw.text((15, (idx*y)-y+10), city, fill=board.BLACK, font=small_font)
-  draw.text((110, (idx*y)-y+7), str(ctime[0]), fill=board.BLACK, font=big_font)
-  draw.text((155, (idx*y)-y+7), str(ctime[1]), fill=board.BLACK, font=big_font)
-  idx += 1
-board.set_image(img)
-board.show()
-```
-And because eInk displays are rather slow to refresh and the clock requires refreshing only once a minute, this can be done through cronjob.
-Before we add this job to cron we need to make `clock.py` executable with `chmod +x clock.py`.
-Then we add a cronjob with `crontab -e`.
-```
-* * * * * /home/pi/clock.py
-```
-So, we end up with a result like this.

-And for the enclosure that can be 3D printed, but I haven't yet something like this can be used.

-You can download my [STL file for the enclosure here](/assets/world-clock/enclosure.stl), but make sure that dimensions make sense and also opening for USB port should be added or just use a drill and some hot glue to make it stick in the enclosure.
