I need to find out whether daylight savings is on now using the new Java 8 datetime classes. I found an entry how to do this in jodatime:
jodatime how to know if daylight savings is on
But how can I find it out in Java 8? (jodatime should be kinda similar but I could not find the corresponding method java.time.ZonedDateTime.isStandardOffset())
Thanks for your help

Most of the United States begins Daylight Saving Time at 2:00 a.m. on the second Sunday in March and reverts to standard time on the first Sunday in November. In the U.S., each time zone switches at a different time. In the European Union, Summer Time begins and ends at 1:00 a.m. Universal Time (Greenwich Mean Time).
In the U.S., daylight saving time starts on the second Sunday in March and ends on the first Sunday in November, with the time changes taking place at 2:00 a.m. local time.
Starting in 2007, DST begins in the U.S. on the second Sunday in March, when people move their clocks forward an hour at 2 a.m. local standard time (so at 2 a.m. on that day, the clocks will then read 3 a.m. local daylight time).
ZoneRules contains the functionality you are intrested in:
public static boolean isDST(ZonedDateTime t) {
return t.getZone().getRules().isDaylightSavings(t.toInstant());
}
