Subject: [RFC PATCH 2/3] pps: Capture PPS timestamps in multiple clocks
Date: Sat, 27 Jun 2026 13:50:27 -0700 [thread overview]
Message-ID: <20260627205028.105252-3-gerikkub@gmail.com> (raw)
In-Reply-To: <20260627205028.105252-1-gerikkub@gmail.com>
Capture the REALTIME, MONOTONIC and BOOTTIME timestamps of all pps
events.
Removes the conditional compilation of ts_raw with the CONFIG_NTP_PPS
option, since now that clock is captured unconditionally.
