The minusNanos() method of OffsetDateTime class in Java returns a copy of this OffsetDateTime with the specified number of nano-seconds subtracted from the parsed date and time.
public OffsetDateTime minusNanos(long nano-seconds)
Parameter: This method accepts a single parameter nano-seconds which specifies the nano-seconds to be subtracted from the parsed date. It can be negative also, in that case, it adds the number of nanoseconds to it.
Return Value: It returns an OffsetDateTime based on this date-time with the nano-seconds subtracted and not null.
Exceptions: The program throws a DateTimeException when it exceeds the supported data and time range.
Below programs illustrate the minusNanos() method:
Date1: 2018-12-12T13:30:30+05:00 Date1 after subtracting nano-seconds: 2018-12-12T13:30:30.000000120+05:00
Date1: 2018-12-12T13:30:30+05:00 Date1 after subtracting nano-seconds: 2018-12-12T13:30:29.999999860+05:00
