Subject: [patch V2 14/26] ntp: Use ktime_get_ntp_seconds()
Date: Mon, 19 May 2025 10:33:31 +0200 (CEST) [thread overview]
Message-ID: <20250519083026.472512636@linutronix.de> (raw)
In-Reply-To: <20250519082042.742926976@linutronix.de>
Use ktime_get_ntp_seconds() to prepare for auxiliary clocks so that
the readout becomes per timekeeper.
