/**
* The LcTime class defines objects in support
* of XFA time picture patterns.
*
*
* The time is internally represented as the number of milliseconds from the
* epoch, which is midnight 00:00:00 GMT, i.e., time 1 is midnight GMT.
*
*
* Time picture patterns are used to parse and format time strings.
* Here are the metasymbols that form valid time picture patterns:
*
* - h
*
- a one or two digit (1-12) hour of AM/PM.
*
- hh
*
- a two digit (01-12) hour of AM/PM.
*
- k
*
- a one or two digit (0-11) hour of AM/PM.
*
- kk
*
- a two digit (00-11) hour of AM/PM.
*
- H
*
- a one or two digit (0-23) hour of day.
*
- HH
*
- a two digit (00-23) hour of day.
*
- K
*
- a one or two digit (1-24) hour of day.
*
- KK
*
- a two digit (01-24) hour of day.
*
- M
*
- a one or two digit (0-59) minute of hour.
*
- MM
*
- a two digit (00-59) minute of hour.
*
- S
*
- a one or two digit (0-59) second of minute.
*
- SS
*
- a two digit (00-59) second of minute.
*
- FFF
*
- a three digit (000-999) thousandth of second.
*
- A
*
- a meridiem name (AM/PM) of the ambient locale.
*
- Z
*
- an abbreviated time zone name of the ambient locale.
*
- z
*
- an ISO8601 time zone format: Z, +HH[MM], -HH[MM].
*
- zz
*
- an alternate ISO8601 time zone format: Z, +HH[:MM], -HH[:MM].
*
*
* Here's a snippet of code illustrating the use of {@link LcTime} to reformat a
* time string
*
*
*
* import com.adobe.xfa.ut.LcTime; // for defn of LcTime.
* ...
* String loc = "en_ca"
* String fmt = LcTime.DEFAULT_TIME_FMT;
* LcTime now = new LcTime(loc);
* now.setLocalTime();
* now += 2 * LcTime.MILLISPERHOUR;
* if (now.isValid())
* System.out.println(now.format("h:MM:SS:FFF A Z"));
