now

open override fun now(): Instant(source)

Returns the Instant corresponding to the current time, according to this clock.

Calling now later is not guaranteed to return a larger Instant. In particular, for Clock.System, the opposite is completely expected, and it must be taken into account. See the System documentation for details.

Even though Instant is defined to be on the UTC-SLS time scale, which enforces a specific way of handling leap seconds, now is not guaranteed to handle leap seconds in any specific way.
