Calcuting the date difference for a specified number of days using LocalDate class

I'm using openjdk version 1.8.0_112-release for development but will need to support previous JDK versions too (pre-Java-8) - so can't use java.time.

I am writing a utitily class to calculate the date to see if a saved date is before the current date which means its expired.

However, I am not sure I have done this the correct way. I am using LocalDate class to calculate the days. The expiration is counted starting from the date and time the user clicked save. That date will be saved and a check will be done against this saved date and time and the current date and time i.e. when the user logs in.

Is this the best way to do it? I would like to keep to the LocalDate class.

import org.threeten.bp.LocalDate;

public final class Utilities {
    private Utilities() {}

    public static boolean hasDateExpired(int days, LocalDate savedDate, LocalDate currentDate) {
        boolean hasExpired = false;

        if(savedDate != null && currentDate != null) {
            /* has expired if the saved date plus the specified days is still before the current date (today) */
            if(savedDate.plusDays(days).isBefore(currentDate)) {
                hasExpired = true;
            }       
        }

        return hasExpired;
    }
}

I'm using the class like this:

private void showDialogToIndicateLicenseHasExpired() {
    final LocalDate currentDate = LocalDate.now();
    final int DAYS_TO_EXPIRE = 3;
    final LocalDate savedDate = user.getSavedDate();

    if(hasDateExpired(DAYS_TO_EXPIRE, savedDate, currentDate)) {
        /* License has expired, warn the user */    
    }
}

I am looking a solution that will take in account time zones. If a license was set to expire in 3 days, and the user was to travel to a different time zone. i.e. they could be ahead or behind based on hours. The license should still expire.
