BTZ

Broadcast Time Zone

btz.sh

#!/bin/sh

# Convert given time to multiple timezones.
# Let people know in other TZs when you intend
# to perform some action.

timezones=('Asia/Hong_Kong' 'Europe/Warsaw' 'Europe/London')
separator=' | '
time_format="%H:%M %Z"

local_date_now=$(date +%s)
local_date_future=$(date -j $1 +%s)

diff=$(expr $((local_date_future-local_date_now)))

[ $diff -lt 0 ] && adjust_prefix="" || adjust_prefix="+"

results=()
for tz in ${timezones[@]}
do
    results+=("$(TZ=$tz date -v $adjust_prefix$diff"S" +"$time_format")")
done

output=$(printf "${separator}%s" "${results[@]}")
output=${output:${#separator}}

echo $output

A tip: you can slap this inside your *rc file and use it as shell function.

btz() {
// body of above Gist
}
