longdateFromFilename(File file, Pattern fileNamePattern, DateFormat dateFormat)
Returns the date embedded in the given file name as milliseconds since the epoch. 
long utc = 0;
Matcher m = fileNamePattern.matcher(file.getName());
if (m.matches()) {
    utc = dateFormat.parse(m.group(1), new ParsePosition(0)).getTime();
return utc;
DatedateFromHourAndMinutes(final String pTime)
Generate from a date object from a given date-string (HH:mm), like 12:13 
final SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");
return sdf.parse(pTime);
DatedateFromISO8601(String iso)
date From ISO 
try {
    String noColon = iso.substring(0, 26) + iso.substring(27);
    return tportResultFormat.parse(noColon);
} catch (ParseException e) {
    throw new RuntimeException("Really unlikely, but it looks like "
            + "travelport is not using ISO dates anymore! " + e.getMessage());
DatedateFromISO8601(String time)
date From ISO 
if (time.length() < 6) {
    return new Date(0);
try {
    if (time.endsWith("Z")) {
        time = time.substring(0, time.length() - 1) + "GMT-00:00";
    } else {
        time = time.substring(0, time.length() - 6) + "GMT"
...
DatedateFromISODate(String isoDate)
date From ISO Date 
TimeZone tz = TimeZone.getTimeZone("UTC");
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.S'Z'");
dateFormat.setTimeZone(tz);
try {
    return dateFormat.parse(isoDate);
} catch (ParseException e) {
    return null;
java.util.DatedateFromString(final String value)
Parses string into a Date object, first attempting as long(millis) then using the SimpleDateFormat: "MM-dd-yyyy" 
java.util.Date d = null;
try {
    d = new java.util.Date();
    d.setTime(Long.parseLong(value));
} catch (NumberFormatException nfe) {

    } catch (ParseException e) {
...

DatedateFromString(String date, String pattern)
