ncasaril opened a new pull request #999: os_time: Prevent 0 ticks returned when OS_TICKS_PER_SEC < 1000
URL: https://github.com/apache/mynewt-core/pull/999
 
 
   The os_time_ms_to_ticks assumes the multiplication always proceeds the division in the following piece of code: 
   
   ```
    ticks = (uint64_t)ms * OS_TICKS_PER_SEC / 1000;
   ```
   
   With an OS_TICKS_PER_SEC < 1000 the division could result in 0 and give the wrong number of ticks. This PR adds () to force multiplication before division. Thus:
   
   ```
    ticks = ((uint64_t)ms * OS_TICKS_PER_SEC) / 1000;
   ```
