Summary

Correction to the @param/@return descriptions of java.time.zone.ZoneRules#isDaylightSavings().

Problem

The description of the argument and the return value of ZoneRules#isDaylightSavings() are incorrect. Looks like merely copied from getStandardOffset().

Solution

Correct those descriptions for daylight savings.

Specification

Change the @param and @return descriptions of the ZoneRules#isDaylightSavings(Instant) method as follows:

-     * @param instant  the instant to find the offset information for, not null, but null
+     * @param instant  the instant to check the daylight savings for, not null, but null
      *  may be ignored if the rules have a single offset for all instants
-     * @return the standard offset, not null
+     * @return true if the specified instant is in daylight savings, false otherwise.
