Comment (by asn):

 Replying to [comment:1 ffmancera]:
 > I am going to work on this patch. This seems to be huge because there is
 a lot of files using timing sources in `src/features/hs`. I am going to
 add some notes in the ticket if there is no problem.

 Agreed that this is an abstract enough task that keeping notes will be
 useful.

 > I saw that we are using `approx_time()` which is an alias of
 `time(NULL)`, but at the same time and in the same file, we are using
 both. As `approx_time.h` has different utilities for timing, we should use
 it instead of `time(NULL)`. What do you think?

 Yes, I think we should be using `approx_time()` instead of `time(NULL)`
 everywhere. I don't see a reason not to.

 One of the problems with HS timing is that lots of the time sources come
 from the main event loop where `time(NULL)` is used.
