    TINYTIME_LAST_CMD=$TINYTIME_RUN_CMD
    TINYTIME_RUN_CMD=$(HISTTIMEFORMAT= history 1);
    if [ "$TINYTIME_LAST_CMD" != "$TINYTIME_RUN_CMD" ]; then
        TINYTIME_RUN_START=$(tinytime epoch);
    fi
}
PS1='$(tinytime $(tinytime epoch)-$TINYTIME_RUN_START) $(tinytime epoch) '$PS1
TINYTIME_RUN_START=$(tinytime epoch)
