   Hmm maybe I do not understand this?
   ```
   struct posix_timer_s
   {
     FAR struct posix_timer_s *flink;
   
     uint8_t         pt_flags;        /* See PT_FLAGS_* definitions */
     uint8_t         pt_crefs;        /* Reference count */
     pid_t           pt_owner;        /* Creator of timer */
     int             pt_delay;        /* If non-zero, used to reset repetitive timers */
     int             pt_last;         /* Last value used to set watchdog */
     WDOG_ID         pt_wdog;         /* The watchdog that provides the timing */
     struct sigevent pt_event;        /* Notification information */
   };
   ```
   But this is my interpretation based on the comments.
   
   `pt_last` should be == `pt_delay` if the timer was repeating. If the timer is not repeating the `pt_delay` will be 0 and only `pt_last` will be valid until the timout.
