Fix: Don't pass ns for ms in timeout during metrics collection

[martin-schulze-e2m]

Description

When nearing the collection deadline, the remaining time should be accurately passed is timeout to the callbacks. Once the deadline is closer than 10s, the remaining time in nanoseconds is passed to timeout_millis, which is expected to be in milliseconds, thus giving a timeout that is 10e6 times too large.
