node: Do not mix monotonic and system time
The struct Epoch introduced in e404f1038f461264f9395742ef74f5b710be
inadvertently made radicle-node suffer from
https://github.com/rust-lang/rust/issues/87906.
That is, updating of the “current time” was skewed way more than expected by a slowly ticking monotonic clock. Such slow ticking can be caused by suspending the system.
