+ The date template represents an interface shell for a date class
+ that is based on a year-month-day system such as the gregorian
+ or iso systems. It provides basic operations to enable calculation
+ and comparisons.
+
+ <b>Theory</b>
+
+ This date representation fundamentally departs from the C tm struct
+ approach. The goal for this type is to provide efficient date
+ operations (add, subtract) and storage (minimize space to represent)
+ in a concrete class. Thus, the date uses a count internally to
+ represent a particular date. The calendar parameter defines
+ the policies for converting the the year-month-day and internal
+ counted form here. Applications that need to perform heavy
+ formatting of the same date repeatedly will perform better
+ by using the year-month-day representation.
+
+ Internally the date uses a day number to represent the date.
+ This is a monotonic time representation. This representation
+ allows for fast comparison as well as simplifying
+ the creation of writing numeric operations. Essentially, the
+ internal day number is like adjusted julian day. The adjustment
+ is determined by the Epoch date which is represented as day 1 of
+ the calendar. Day 0 is reserved for negative infinity so that
+ any actual date is automatically greater than negative infinity.
+ When a date is constructed from a date or formatted for output,
+ the appropriate conversions are applied to create the year, month,
+ day representations.

+ /*! The csv file containing the zone_specs used by the
+ * tz_db_base is intended to be customized by the
+ * library user. When customizing this file (or creating your own) the
+ * file must follow a specific format.
+ *
+ * This first line is expected to contain column headings and is therefore
+ * not processed by the tz_db_base.
+ *
+ * Each record (line) must have eleven fields. Some of those fields can
+ * be empty. Every field (even empty ones) must be enclosed in
+ * double-quotes.
+ * Ex:
+ * @code
+ * "America/Phoenix" <- string enclosed in quotes
+ * "" <- empty field
+ * @endcode
+ *
+ * Some fields represent a length of time. The format of these fields
+ * must be:
+ * @code
+ * "{+|-}hh:mm[:ss]" <- length-of-time format
+ * @endcode
+ * Where the plus or minus is mandatory and the seconds are optional.
+ *
+ * Since some time zones do not use daylight savings it is not always
+ * necessary for every field in a zone_spec to contain a value. All
+ * zone_specs must have at least ID and GMT offset. Zones that use
+ * daylight savings must have all fields filled except:
+ * STD ABBR, STD NAME, DST NAME. You should take note
+ * that DST ABBR is mandatory for zones that use daylight savings
+ * (see field descriptions for further details).
+ *
+ * ******* Fields and their description/details *********
+ *
+ * ID:
+ * Contains the identifying string for the zone_spec. Any string will
+ * do as long as it's unique. No two ID's can be the same.
+ *
+ * STD ABBR:
+ * STD NAME:
+ * DST ABBR:
+ * DST NAME:
+ * These four are all the names and abbreviations used by the time
+ * zone being described. While any string will do in these fields,
+ * care should be taken. These fields hold the strings that will be
+ * used in the output of many of the local_time classes.
+ * Ex:
+ * @code
+ * time_zone nyc = tz_db.time_zone_from_region("America/New_York");
+ * local_time ny_time(date(2004, Aug, 30), IS_DST, nyc);
+ * cout << ny_time.to_long_string() << endl;
+ * // 2004-Aug-30 00:00:00 Eastern Daylight Time
+ * cout << ny_time.to_short_string() << endl;
+ * // 2004-Aug-30 00:00:00 EDT
+ * @endcode
+ *
+ * NOTE: The exact format/function names may vary - see local_time
+ * documentation for further details.
+ *
+ * GMT offset:
+ * This is the number of hours added to utc to get the local time
+ * before any daylight savings adjustments are made. Some examples
+ * are: America/New_York offset -5 hours, & Africa/Cairo offset +2 hours.
+ * The format must follow the length-of-time format described above.
+ *
+ * DST adjustment:
+ * The amount of time added to gmt_offset when daylight savings is in
+ * effect. The format must follow the length-of-time format described
+ * above.
+ *
+ * DST Start Date rule:
+ * This is a specially formatted string that describes the day of year
+ * in which the transition take place. It holds three fields of it's own,
+ * separated by semicolons.
+ * The first field indicates the "nth" weekday of the month. The possible
+ * values are: 1 (first), 2 (second), 3 (third), 4 (fourth), 5 (fifth),
+ * and -1 (last).
+ * The second field indicates the day-of-week from 0-6 (Sun=0).
+ * The third field indicates the month from 1-12 (Jan=1).
+ *
+ * Examples are: "-1;5;9"="Last Friday of September",
+ * "2;1;3"="Second Monday of March"
+ *
+ * Start time:
+ * Start time is the number of hours past midnight, on the day of the
+ * start transition, the transition takes place. More simply put, the
+ * time of day the transition is made (in 24 hours format). The format
+ * must follow the length-of-time format described above with the
+ * exception that it must always be positive.
+ *
+ * DST End date rule:
+ * See DST Start date rule. The difference here is this is the day
+ * daylight savings ends (transition to STD).
+ *
+ * End time:
+ * Same as Start time.
