# Execution time tracking hooks, this is unique to zsh, as it can add
# preexec and precmd hooks. We can utilize this to keep track of the
# amount of time it took to run certain command. We store the start time
# within a variable: PROMPT_EXEC_TIME_START, which we then compare and
# unset after the command was finished. In here, we simply set the
# PROMPT_EXEC_TIME_DURATION, which is then used in the actual prompt
# This will only be enabled if SHOW_CMD_TIME is 1.
