30-hour clock is good, so display it on your i3bar

trigesimal.py

# A simple py3status module to display datetime on your i3bar as if there are 30 hours every day

# Usage: store this file as ~/.config/py3status/modules/trigesimal.py (or in directory storing 
# py3status modules), then append `order += 'trigesimal'` to your py3status config file

# Timezone and locale setting is left to the user as a beneficial exercise.

    def trigesimal(self):
        d = datetime.datetime.now()
        hour = d.hour
        if hour < 6:
            d -= datetime.timedelta(days=1)
            hour += 24
        weekday = ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'][d.weekday()]
        result = f'{d.year:04}-{d.month:02}-{d.day:02} {hour:02}:{d.minute:02}:{d.second:02} {weekday}'
