Ridiculously contribed BitBar clock that displays rounded time as an emoji

time.1s.sh

#!/bin/sh

function clock_emoji {
    time_hour=$1
    time_minute=$2

    # Round to 30-minute intervals
    time_minute=$(( (time_minute + 15) / 30 * 30 ))

    # If we've rounded up, move to next hour (checking for overflow)
    if [ $time_minute == 60 ]; then
        time_minute=0
        time_hour=$(($time_hour+1))
        if [ $time_hour = 13 ]; then
            time_hour=1
        fi
    fi

    # Empty minutes if minutes is zero
    if [ $time_minute = 0 ]; then
        time_minute=""
    fi

    printf ":clock%s%s:" $time_hour $time_minute
}

time_hour=$(( 0 + `date "+%l"` ))
time_minute=$(( 0 + `date "+%M"` ))
am_pm=$(date "+%p")

face=$(clock_emoji $time_hour $time_minute)

printf "%s %s:%02d %s\n" $face $time_hour $time_minute $am_pm
echo "---"
date "+%A, %e %B %Y"
