+ Constructor.
+ \param isNulleable Indica si el dato puede tomar valores nulos.
+ \param format Formato usado para interpretar los datos de esta fecha, en los metodos Date::getCStringValue y
+ Date::setValue (const char*) y Date::setValue (const std::string&). Sigue la especificacion:
+
+ \code
+ %a Replaced by the localeâs abbreviated weekday name. [ tm_wday]
+
+ %A Replaced by the localeâs full weekday name. [ tm_wday]
+
+ %b Replaced by the localeâs abbreviated month name. [ tm_mon]
+
+ %B Replaced by the localeâs full month name. [ tm_mon]
+
+ %c Replaced by the locale's appropriate date and time representation. (See the Base Definitions volume of
+ IEEE Std 1003.1-2001, <time.h>.)
+
+ %C Replaced by the year divided by 100 and truncated to an integer, as a decimal number [00,99]. [ tm_year]
+
+ %d Replaced by the day of the month as a decimal number [01,31]. [ tm_mday]
+
+ %D Equivalent to %m / %d / %y . [ tm_mon, tm_mday, tm_year]
+
+ %e Replaced by the day of the month as a decimal number [1,31]; a single digit is preceded by a space. [
+ tm_mday]
+
+ %F Equivalent to %Y - %m - %d (the ISO 8601:2000 standard date format). [ tm_year, tm_mon, tm_mday]
+
+ %g Replaced by the last 2 digits of the week-based year (see below) as a decimal number [00,99]. [ tm_year,
+ tm_wday, tm_yday]
+
+ %G Replaced by the week-based year (see below) as a decimal number (for example, 1977). [ tm_year, tm_wday,
+ tm_yday]
+
+ %h Equivalent to %b . [ tm_mon]
+
+ %H Replaced by the hour (24-hour clock) as a decimal number [00,23]. [ tm_hour]
+
+ %I Replaced by the hour (12-hour clock) as a decimal number [01,12]. [ tm_hour]
+
+ %j Replaced by the day of the year as a decimal number [001,366]. [ tm_yday]
+
+ %m Replaced by the month as a decimal number [01,12]. [ tm_mon]
+
+ %M Replaced by the minute as a decimal number [00,59]. [ tm_min]
+
+ %n Replaced by a <newline>.
+
+ %p Replaced by the locale's equivalent of either a.m. or p.m. [ tm_hour]
+
+ %r Replaced by the time in a.m. and p.m. notation; in the POSIX locale this shall be equivalent to %I : %M
+ : %S %p . [ tm_hour, tm_min, tm_sec]
+
+ %R Replaced by the time in 24-hour notation ( %H : %M ). [ tm_hour, tm_min]
+
+ %S Replaced by the second as a decimal number [00,60]. [ tm_sec]
+
+ %t Replaced by a <tab>.
+
+ %T Replaced by the time ( %H : %M : %S ). [ tm_hour, tm_min, tm_sec]
+
+ %u Replaced by the weekday as a decimal number [1,7], with 1 representing Monday. [ tm_wday]
+
+ %U Replaced by the week number of the year as a decimal number [00,53]. The first Sunday of January is the
+ first day of week 1; days in the new year before this are in week 0. [ tm_year, tm_wday, tm_yday]
+
+ %V Replaced by the week number of the year (Monday as the first day of the week) as a decimal number [01,53].
+ If the week containing 1 January has four or more days in the new year, then it is considered week 1. Oth-
+ erwise, it is the last week of the previous year, and the next week is week 1. Both January 4th and the
+ first Thursday of January are always in week 1. [ tm_year, tm_wday, tm_yday]
+
+ %w Replaced by the weekday as a decimal number [0,6], with 0 representing Sunday. [ tm_wday]
+
+ %W Replaced by the week number of the year as a decimal number [00,53]. The first Monday of January is the
+ first day of week 1; days in the new year before this are in week 0. [ tm_year, tm_wday, tm_yday]
+
+ %x Replaced by the locale's appropriate date representation. (See the Base Definitions volume of
+ IEEE Std 1003.1-2001, <time.h>.)
+
+ %X Replaced by the locale's appropriate time representation. (See the Base Definitions volume of
+ IEEE Std 1003.1-2001, <time.h>.)
+
+ %y Replaced by the last two digits of the year as a decimal number [00,99]. [ tm_year]
+
+ %Y Replaced by the year as a decimal number (for example, 1997). [ tm_year]
+
+ %z Replaced by the offset from UTC in the ISO 8601:2000 standard format ( +hhmm or -hhmm ), or by no charac-
+ ters if no timezone is determinable. For example, "-0430" means 4 hours 30 minutes behind UTC (west of
+ Greenwich). If tm_isdst is zero, the standard time offset is used. If tm_isdst is greater than zero, the
+ daylight savings time offset is used. If tm_isdst is negative, no characters are returned. [ tm_isdst]
+
+ %Z Replaced by the timezone name or abbreviation, or by no bytes if no timezone information exists. [
+ tm_isdst]
+
+ %% Replaced by % .
