Method TimeDiff

event.go:807–817

TimeDiff adds the field key with positive duration between time t and start. If time t is not greater than start, duration will be 0. Duration format follows the same principle as Dur().

(key string, t time.Time, start time.Time)

// If time t is not greater than start, duration will be 0.
// Duration format follows the same principle as Dur().

	e.buf = enc.AppendDuration(enc.AppendKey(e.buf, key), d, DurationFieldUnit, DurationFieldFormat, DurationFieldInteger, FloatingPointPrecision)
	return e

// Any is a wrapper around Event.Interface.
