Your formatting string can contain anything you like, however certain sequences are considered placeholders, and will be replaced by corresponding values. Non-placeholders are returned unprocessed

Examples

Format current date, time as it is in GMT zone, using 24hrs clock format:

TimeZone tz = TimeZone.getTimeZone("GMT");
Calendar c = new GregorianCalendar(tz);
c.setTime(new Date());

String formatted = DateTimeTemplate.format(c, "GMT: %DD% %hh%:%ii%");

would produce GMT: Mon 16:25.

Format current time as it is in Pacific Daylight Time zone ( PDT is 7 hours behind GMT), using 12hrs clock format with abbreviated AM/PM marker:

TimeZone tz = TimeZone.getTimeZone("GMT-0700");
Calendar c = new GregorianCalendar(tz);
c.setTime(new Date());

String formatted = DateTimeTemplate.format(c, "Time: %k%:%ii%%a%");

would produce Time: 3:25a.

Format current time using device's time zone:

TimeZone tz = TimeZone.getDefault();
Calendar c = new GregorianCalendar(tz);
c.setTime(new Date());

String formatted = DateTimeTemplate.format(c, ...);

Formatting using locale of your choice:

String formatted = DateTimeTemplate.format(cal, "Time: %k%:%ii%%a%", Locale.SIMPLIFIED_CHINESE);
