Comment(by cjb):

 Well, we can infer a small amount:

 {{{
  0) ! 125535244 us |            } /* schedule */
  0) ! 125535250 us |          } /* schedule_hrtimeout_range_clock */
  0) ! 125535262 us |        } /* schedule_hrtimeout_range */
  0) ! 125535267 us |      } /* poll_schedule_timeout */
 }}}

 That's two minutes, so it seems like schedule()s timing is messed up.
