Merge branch 'maint-17' into maint

The diffs are all about adapting to the OTP 18 time interface. The code
was previously backwards compatible, falling back on the erlang:now/0 if
erlang:monotonic_time/0 is unavailable, but this was seen to be a bad
thing in commit 9c0f2f2c. Use of erlang:now/0 is now removed.
