In fact, the current `DateTimeFormatterBuilder.InstantPrinterParser` already
use different behavior for formatting, i.e., only print time in "Z" (no offset).
The following change:
--- a/src/java.base/share/classes/java/time/format/DateTimeFormatterBuilder.java
+++ b/src/java.base/share/classes/java/time/format/DateTimeFormatterBuilder.java
@@ -3887,7 +3887,7 @@ public int parse(DateTimeParseContext context,
CharSequence text, int position)
.appendValue(MINUTE_OF_HOUR, 2).appendLiteral(':')
.appendValue(SECOND_OF_MINUTE, 2)
.appendFraction(NANO_OF_SECOND, minDigits, maxDigits, true)
- .appendOffsetId()
+ .appendOffset("+HH:mm:ss", "Z")
.toFormatter().toPrinterParser(false);
DateTimeParseContext newContext = context.copy();
int pos = parser.parse(newContext, text, position);
will parse hour-only offset for `Instant.parse()` but I am not sure we would go
for this, as other `ISO` formatters all use "MM" for minutes. @jodastephen any
suggestions?
