commit b08409cd3b07c65696044c28702af88b6966d232
Author: Yukai Chou <muzimuzhi at gmail.com>
Date:   Fri Sep 15 22:55:55 2023 +0800

    Add docu for `\sys_if_timer_exist_p:` and `\sys_if_timer_exist:(TF)`
    
    They were added by commit 1867e95 (Move timer to sys, 2020-10-05),
    as part of PR #859 which was merged on 2021-05-12.
    
    The added date is set to 2021-05-12, the merged date, because the
    commit date (2020-10-05) and current added date of `\sys_timer:`
    (2020-09-24) are both quite prior to merged date of such commit.
