| * <p> |
| * If only a (standard zone name) is given (no numbers in the |
| * String) then it gets mapped directly to the TimeZone with that |
| * name, if that fails null is returned. |
| * <p> |
| * A GMT offset is the offset to add to the local time to get GMT. |
| * If a (GMT offset) is included (either in seconds or hours) then |
| * an attempt is made to find a TimeZone name matching both the name |
| * and the offset (that doesn't observe daylight time, if the |
| * timezone observes daylight time then you must include a daylight |
| * time zone name after the offset), if that fails then a TimeZone |
| * with the given GMT offset is returned (whether or not the |
| * TimeZone observes daylight time is ignored), if that also fails |
| * the GMT TimeZone is returned. |
| * <p> |
| * If the String ends with (GMT offset)(daylight time zone name) |
| * then an attempt is made to find a TimeZone with the given name and |
| * GMT offset that also observes (the daylight time zone name is not |
| * currently used in any other way), if that fails a TimeZone with |
| * the given GMT offset that observes daylight time is returned, if |
| * that also fails the GMT TimeZone is returned. |
| * <p> |
| * Examples: In Chicago, the time zone id could be "CST6CDT", but |
| * the preferred name would be "America/Chicago". In Indianapolis |
| * (which does not have Daylight Savings Time) the string could be |
| * "EST5", but the preferred name would be "America/Indianapolis". |
| * The standard time zone name for The Netherlands is "Europe/Amsterdam", |
