Re: WG: Need for HW-clock independent timestamps

I really appreciate the resumption. Whatever mechanisms wireguard introduces to handle non-RTC devices with limited flash-write cycles (which far most of the openWrt community uses) would significantly ease the configuration of every-even-ntp-traffic-secured networks. Regarding > Initiation of

Hello, With regards to the subject, ...to discuss the demand and identify solutions for a "HW-clock INDEPENDENT WG solution", I've seen essentially three different suggestions so fare: a) Buy and connect a HW clock. IMO: Often difficult considering available HW, budget, and skills. b) Rely on th

Hello, We have the following chicken-egg problem: We are using WG on openwrt devices which do not have a hardware clock so that time is resetted after each reboot. Because internet access shall be routed via WG tunnels the internet and network-time services (NTP) is not available unless WG works p
