Argument

Description

from

the first timestamp

the second timestamp

the number of microseconds between the two timestamps (positive if `to` is after `from` except in case of overflow)

be careful when diffing against large timestamps (e.g. at_the_end_of_time ) as the signed integer may overflow.
