From c204c4ab449e9eae4e2f6be2e798196711ccc585 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Toke=20H=C3=B8iland-J=C3=B8rgensen?= Date: Tue, 19 Apr 2022 00:24:14 +0200 Subject: [PATCH] lib/timer: Add current_time_now() function for immediate timestamp MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a current_time_now() function which gets an immediate monotonic timestamp instead of using the cached value from the event loop. This is useful for callers that need precise times, such as the Babel RTT measurement code.
