<p><a class="el" href="classGlib_1_1DateTime.html" title="DateTime - A structure representing Date and Time. ">DateTime</a> is a structure that combines a Gregorian date and time into a single structure. It provides many conversion and methods to manipulate dates and times. Time precision is provided down to microseconds and the time can range (proleptically) from 0001-01-01 00:00:00 to 9999-12-31 23:59:59.999999. <a class="el" href="classGlib_1_1DateTime.html" title="DateTime - A structure representing Date and Time. ">DateTime</a> follows POSIX time in the sense that it is oblivious to leap seconds.</p>
<p><a class="el" href="classGlib_1_1DateTime.html" title="DateTime - A structure representing Date and Time. ">DateTime</a> is an immutable object; once it has been created it cannot be modified further. All modifiers will create a new <a class="el" href="classGlib_1_1DateTime.html" title="DateTime - A structure representing Date and Time. ">DateTime</a>. Nearly all such functions can fail due to the date or time going out of range, in which case <code>0</code> will be returned.</p>
<p><a class="el" href="classGlib_1_1DateTime.html" title="DateTime - A structure representing Date and Time. ">DateTime</a> is reference counted. When the reference count drops to 0, the resources allocated by the <a class="el" href="classGlib_1_1DateTime.html" title="DateTime - A structure representing Date and Time. ">DateTime</a> structure are released.</p>
<p>Many parts of the API may produce non-obvious results. As an example, adding two months to January 31st will yield March 31st whereas adding one month and then one month again will yield either March 28th or March 29th. Also note that adding 24 hours is not always the same as adding one day (since days containing daylight savings time transitions are either 23 or 25 hours in length). </p><dl class="since_2_30"><dt><b><a class="el" href="since_2_30.html#_since_2_30000001">Since glibmm 2.30:</a></b></dt><dd></dd></dl>

<p>Creates a newly allocated string representing the requested <em>format</em>. </p>
<p>The format strings understood by this function are a subset of the strftime() format language as specified by C99. The \D, \U and \W conversions are not supported, nor is the 'E' modifier. The GNU extensions \k, \l, \s and \P are supported, however, as are the '0', '_' and '-' modifiers.</p>
<p>In contrast to strftime(), this function always produces a UTF-8 string, regardless of the current locale. Note that the rendering of many formats is locale-dependent and may not match the strftime() output exactly.</p>
<p>The following format specifiers are supported:</p>
<ul>
<li>\a: the abbreviated weekday name according to the current locale</li>
<li>\A: the full weekday name according to the current locale</li>
<li>\b: the abbreviated month name according to the current locale</li>
<li>\B: the full month name according to the current locale</li>
<li>\c: the preferred date and time rpresentation for the current locale</li>

<li>\d: the day of the month as a decimal number (range 01 to 31)</li>
<li>\e: the day of the month as a decimal number (range 1 to 31)</li>
<li>\F: equivalent to <code>Y-m-d</code> (the ISO 8601 date format)</li>
<li>\g: the last two digits of the ISO 8601 week-based year as a decimal number (00-99). This works well with \V and \u.</li>
<li>\G: the ISO 8601 week-based year as a decimal number. This works well with \V and \u.</li>
<li>\h: equivalent to \b</li>
<li>\H: the hour as a decimal number using a 24-hour clock (range 00 to 23)</li>
<li>\I: the hour as a decimal number using a 12-hour clock (range 01 to 12)</li>
<li>\j: the day of the year as a decimal number (range 001 to 366)</li>
<li>\k: the hour (24-hour clock) as a decimal number (range 0 to 23); single digits are preceded by a blank</li>
<li>\l: the hour (12-hour clock) as a decimal number (range 1 to 12); single digits are preceded by a blank</li>
<li>\m: the month as a decimal number (range 01 to 12)</li>
<li>\M: the minute as a decimal number (range 00 to 59)</li>
<li>\p: either "AM" or "PM" according to the given time value, or the corresponding strings for the current locale. Noon is treated as "PM" and midnight as "AM".</li>
<li>\P: like \p but lowercase: "am" or "pm" or a corresponding string for the current locale</li>
<li>\r: the time in a.m. or p.m. notation</li>
<li>\R: the time in 24-hour notation (\H:\M)</li>
<li>\s: the number of seconds since the Epoch, that is, since 1970-01-01 00:00:00 UTC</li>
<li>\S: the second as a decimal number (range 00 to 60)</li>
<li>\t: a tab character</li>
<li>\T: the time in 24-hour notation with seconds (\H:\M:\S)</li>
<li>\u: the ISO 8601 standard day of the week as a decimal, range 1 to 7, Monday being 1. This works well with \G and \V.</li>
<li>\V: the ISO 8601 standard week number of the current year as a decimal number, range 01 to 53, where week 1 is the first week that has at least 4 days in the new year. See g_date_time_get_week_of_year(). This works well with \G and \u.</li>
<li>\w: the day of the week as a decimal, range 0 to 6, Sunday being 0. This is not the ISO 8601 standard format – use \u instead.</li>
<li>\x: the preferred date representation for the current locale without the time</li>
<li>\X: the preferred time representation for the current locale without the date</li>
<li>\y: the year as a decimal number without the century</li>
<li>\Y: the year as a decimal number including the century</li>

<p>Some conversion specifications can be modified by preceding the conversion specifier by one or more modifier characters. The following modifiers are supported for many of the numeric conversions:</p>
<ul>
<li>O: Use alternative numeric symbols, if the current locale supports those.</li>

<li>-: Do not pad a numeric result. This overrides the default padding for the specifier.</li>

<p>This function, taken together with g_date_time_get_week_of_year() and g_date_time_get_day_of_week() can be used to determine the full ISO week date on which <em>datetime</em> falls.</p>
<p>This is usually equal to the normal Gregorian year (as returned by g_date_time_get_year()), except as detailed below:</p>
<p>For Thursday, the week-numbering year is always equal to the usual calendar year. For other days, the number is such that every day within a complete week (Monday to Sunday) is contained within the same week-numbering year.</p>
<p>For Monday, Tuesday and Wednesday occurring near the end of the year, this may mean that the week-numbering year is one greater than the calendar year (so that these days have the same week-numbering year as the Thursday occurring early in the next year).</p>
<p>For Friday, Saturaday and Sunday occurring near the start of the year, this may mean that the week-numbering year is one less than the calendar year (so that these days have the same week-numbering year as the Thursday occurring late in the previous year).</p>
<p>An equivalent description is that the week-numbering year is equal to the calendar year containing the majority of the days in the current week (Monday to Sunday).</p>
<p>Note that January 1 0001 in the proleptic Gregorian calendar is a Monday, so this function never returns 0.</p>
