Android's date time value fix based on timezone differences.

timezone-fix.java

// Needed
import java.util.Calendar;
import java.util.TimeZone;

// Initialize calendar instance and set your datetime value
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(dateTimeValue);

// Initialize timezone with your timezone value
TimeZone tz = TimeZone.getTimeZone("America/New_York");

// Get the correct time
// Time - TimeZone difference - TimeZone Daylight Savings difference
long fixedDateTime = cal.getTimeInMillis() - tz.getRawOffset() - tz.getDSTSavings();
