Java Time API

[delanym]

Is there any plan to use the new Java Time API? I see Calendar is still used in Field32A for example.

Hi @delanym, thanks for asking.

The date/time components still use java.util.Calendar, and Date in a few places, for backward-compatibility reasons.

There is no immediate plan to change those types because they are part of the public API and are used by many downstream projects.

That said, converting to java.time on your side is straightforward:

Field32A f = mt.getField32A();

// From the Calendar accessor
Calendar cal = f.getDateAsCalendar();

LocalDate date = (cal == null) ? null
        : LocalDate.of(
                cal.get(Calendar.YEAR),
                cal.get(Calendar.MONTH) + 1,
                cal.get(Calendar.DAY_OF_MONTH)
        );

// Or directly from the raw component: yyMMdd for field 32A
LocalDate date2 = LocalDate.parse(
        f.getComponent1(),
        DateTimeFormatter.ofPattern("yyMMdd")
);
