 \bt_p{offset_seconds} can be negative. For example, considering:
 
 - A 1000 Hz clock.
-- \bt_p{offset_seconds} set to -10 seconds.
+- \bt_p{offset_seconds} set to −10 seconds.
 - \bt_p{offset_cycles} set to 500 cycles
   (that is, 0.5 seconds).
 - \bt_p{cycles} set to 2000 cycles (that is, 2 seconds).
 
-The computed value is -7.5 seconds, so this function sets
-\bt_p{*ns_from_origin} to -7,500,000,000.
