convert TimeUtil.java to TimeUtil.js, URI_Template.java to URI_Template.js

[jbfaden]

TimeUtil.java was always intended to be ported to other languages, and I'm curious how the port to JavaScript would go. I've been using the site https://www.jsweet.org/jsweet-live-sandbox/ to convert the code piece by piece, because it isn't working for the entire code, and it produces somewhat unreadable code anyway.

This is a table of function name in Java and if it is ported to JavaScript:

Java	JavaScript
final int TIME_DIGITS = 7;	Y
final int DATE_DIGITS = 3;	Y
String reformatIsoTime(String exampleForm, String time)	Y
String monthNameAbbrev(int i)	Y
int monthNumber(String s) throws ParseException	Y
String[] countOffDays(String startTime, String stopTime)	Y
String nextDay(String day)	Y
String previousDay(String day)	Y
String ceil(String time)	Y
String floor(String time)	Y
String normalizeTimeString(String time)	Y
String isoTimeFromArray(int[] nn)	Y
String formatIso8601TimeRange( int[] nn )	Y
String formatIso8601Time( int[] nn, int offset )	Y
String formatIso8601Time( int[] nn )	Y
String formatIso8601Duration(int[] nn)	Y
int[] now()	Y
int[] isoTimeToArray(String time)	Y
int dayOfYear(int year, int month, int day)	Y
int monthForDayOfYear( int year, int doy )	Y
long toMillisecondsSince1970(String time)	Y
void normalizeTime(int[] time)	Y
int dayOfWeek( int year, int month, int day )	Y
void fromWeekOfYear( int year, int weekOfYear, int[] time )	Y
int[] parseISO8601Duration(String stringIn)	Y
int[] parseISO8601Time( String string )	Y
int[] parseISO8601TimeRange(String stringIn)	Y
int julianDay(int year, int month, int day)	Y
int[] fromJulianDay(int julian)	Y
int[] subtract(int[] base, int[] offset)	Y
int[] add(int[] base, int[] offset)	Y

@rweigel and I were using jsweet last week, but I've also just found https://www.stratacode.com/javaToJS/online.html. This one allows multiple Java classes to be uploaded (TimeUtil.java is needed for URI_Templates to work).

I had an unusual opportunity to work on this last week (Covid!) and I made a translator similar to the Python translator. This is done enough to easily do TimeUtil.js now, and the unit test for TimeUtil.js. The converter is here: https://cottagesystems.com/JavaJythonConverter/ConvertJavaToJavascriptServlet. I need to return to this and finish off URI_Templates.java.

This is done, or at least passing all the regression tests.
