The following formats are not available in Date Time Formats:
C	century of era (>=0)	number	20
K	hour of halfday (0~11)	number	3
KK	hour of halfday (0~11)	number	03
k	clockhour of day (1~24)	number	14
kk	clockhour of day (1~24)	number	14
The following format is not available for use in toString, which will instead return the same as Z. The time zones supported will be dependent on your server settings. Unsupported time zones will result in an error during analysis.
z	time zone	text	PST

The number of letters used in the pattern determines the format.

Text: If the number of pattern letters is 4 or more, the full form is used; otherwise a short or abbreviated form is used if available.
Number: The minimum number of digits. Shorter numbers are zero-padded to this amount.
Year: Numeric presentation for year and weekyear fields are handled specially. For example, if the count of 'y' is 2, the year will be displayed as the zero-based year of the century, which is two digits.
Month: 3 or over, use text, otherwise use number.
Zone: 'Z' outputs offset without a colon, 'ZZ' outputs the offset with a colon, 'ZZZ' or more outputs the zone id.
Any characters in the pattern that are not in the ranges of ['a'..'z'] and ['A'..'Z'] will be treated as quoted text. For instance, characters like ':', '.', ' ', '#' and '?' will appear in the resulting time text even they are not embraced within single quotes.
