Comment (by 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.

 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?
