Subject: [PATCH nft 0/4] add operation cache for timestamp
Date: Fri, 25 Aug 2023 15:24:16 +0200 [thread overview]
Message-ID: <20230825132942.2733840-1-thaller@redhat.com> (raw)
Add a cache for "time(NULL)" and tm_gmtoff from localtime_r(time(NULL), &tm).
The point is to ensure that one parse/output operation fetches the current time
and GMT offset at most once.
