# A xpybar configuration example that demonstrates how you can
# write a configuration that lets you change the clock between
# any timezone you want using the keyboard or terminal.
# This example requires the package python-posix_ipc, and the
# example command requires the package cmdipc.
# Caveat: This example is only written to support local displays.
# If the host part of $DISPLAY contains a dot, this example will
# not work as expected.
# Caveat: The IPC objects are not cleaned up on exit.
# After exiting you may want to run
# cmdipc -PQrk "/~${USER}.xpybar.$(echo "${DISPLAY}" | cut -d . -f 1)"
# To switch between UTC and localtime run the command
# cmdipc -PQk "/~${USER}.xpybar.$(echo "${DISPLAY}" | cut -d . -f 1)" send -- tz ${THE_TIMEZONE_YOU_WANT}
# You may want to add an executable file in your ~/.local/bin
# (which should you include in your $PATH) containing the code
# #!/bin/sh
# exec cmdipc -PQk "/~${USER}.xpybar.$(echo "${DISPLAY}" | cut -d . -f 1)" send -- tz "$@"
# You can then add a hotkey to xbindkeys running that command
# with a timezone as a argument, or run it in the terminal.
# If the timezone is omitted, local time is used.
