You could use the java.time.ZoneDateTime#ofInstant() method:

import java.time.*;

public class TimeZonesConversion {
    static ZonedDateTime convert(ZonedDateTime time, ZoneId newTimeZone) {
        return ZonedDateTime.ofInstant(
                time.toInstant(),
                newTimeZone);
    };

    public static void main(String... args) {
        ZonedDateTime mstTime = ZonedDateTime.of(LocalDateTime.now(), ZoneId.of("-07")); 
        ZonedDateTime localTime = convert(mstTime, Clock.systemDefaultZone().getZone());
        System.out.println("MST(" + mstTime + ") = " + localTime);
    }
}
