Gets the value of {\tt time} in units specified by the user ! via Fortran optional arguments. See {\tt ESMF\_TimeSet()} above for a ! description of time units and calendars. ! ! The ESMF Time Manager represents and manipulates time internally with ! integers to maintain precision. Hence, user-specified floating point ! values are converted internally from integers. For example, if a time ! value is 5 and 3/8 seconds (s=5, sN=3, sD=8), and you want to get it as ! floating point seconds, you would get 5.375 (s\_r8=5.375). ! ! Units are bound (normalized) by the next larger unit specified. For ! example, if a time is defined to be 2:00 am on February 2, 2004, then ! {\tt ESMF\_TimeGet(dd=day, h=hours, s=seconds)} would return ! {\tt day = 2}, {\tt hours = 2}, {\tt seconds = 0}, ! whereas {\tt ESMF\_TimeGet(dd = day, s=seconds)} would return ! {\tt day = 2}, {\tt seconds = 7200}. ! Note that {\tt hours} and {\tt seconds} are bound by a day. If bound ! by a month, ! {\tt ESMF\_TimeGet(mm=month, h=hours, s=seconds)} would return ! {\tt month = 2}, {\tt hours = 26}, {\tt seconds = 0}, ! and {\tt ESMF\_TimeGet(mm = month, s=seconds)} would return ! {\tt month = 2}, {\tt seconds = 93600} (26 * 3600). ! Similarly, if bound to a year, ! {\tt ESMF\_TimeGet(yy=year, h=hours, s=seconds)} would return ! {\tt year = 2004}, {\tt hours = 770} (32*24 + 2), {\tt seconds = 0}, ! and {\tt ESMF\_TimeGet(yy = year, s=seconds)} would return ! {\tt year = 2004}, {\tt seconds = 2772000} (770 * 3600). ! ! For {\tt timeString}, {\tt timeStringISOFrac}, {\tt dayOfWeek}, ! {\tt midMonth}, {\tt dayOfYear}, {\tt dayOfYear\_intvl}, and ! {\tt dayOfYear\_r8} described below, valid calendars are Gregorian, ! Julian, No Leap, 360 Day and Custom calendars. Not valid for ! Julian Day, Modified Julian Day, or No Calendar. \\ ! ! For {\tt timeString} and {\tt timeStringISOFrac}, YYYY format returns ! at least 4 digits; years <= 999 are padded on the left with zeroes and ! years >= 10000 return the number of digits required. ! ! For timeString, convert {\tt ESMF\_Time}'s value into partial ISO 8601 ! format YYYY-MM-DDThh:mm:ss[:n/d]. See ~\cite{ISO} and ~\cite{ISOnotes}. ! See also method {\tt ESMF\_TimePrint()}. ! !

Initializes an {\tt ESMF\_Time} with a set of user-specified units ! via Fortran optional arguments. ! ! The range of valid values for mm and dd depend on the calendar used. ! For Gregorian, Julian, and No-Leap calendars, mm is [1-12] and dd is ! [1-28,29,30, or 31], depending on the value of mm and whether yy or ! yy\_i8 is a leap year. For the 360-day calendar, mm is [1-12] and dd is ! [1-30]. For the Julian-day, Modified Julian-day, and No-calendar, ! yy, yy\_i8, mm, and dd are invalid inputs, since these calendars do not ! define them. When valid, the yy and yy\_i8 arguments should be fully ! specified, e.g. 2003 instead of 03. yy and yy\_i8 ranges are only ! limited by machine word size, except for the Gregorian and Julian ! calendars, where the lowest (proleptic) date limits are 3/1/-4800 and ! 3/1/-4712, respectively. This is a limitation of the Gregorian ! date-to-Julian day and Julian date-to-Julian day conversion algorithms ! used to convert Gregorian and Julian dates to the internal representation ! of seconds. See~\cite{Fli68} for a description of the Gregorian ! date-to-Julian day algorithm and~\cite{Hat84} for a description of the ! Julian date-to-Julian day algorithm. The Custom calendar will have ! user-defined values for yy, yy\_i8, mm, and dd. ! ! The Julian day specifier, d or d\_i8, can only be used with the ! Julian-day and Modified Julian Day calendars, and has a valid range ! depending on the word size. For a signed 32-bit d, the range for ! Julian-day is [+/- 24855]. For a signed 64-bit d or d\_i8, the valid ! range for Julian-day is [+/- 106,751,991,167,300]. The Julian day ! number system adheres to the conventional standard where the reference ! day of d=0 corresponds to 11/24/-4713 in the proleptic Gregorian calendar ! and 1/1/-4712 in the proleptic Julian calendar. See~\cite{Meyer2} and ! ~\cite{JDNcalculator}. ! ! The Modified Julian Day, introduced by space scientists in the late ! 1950's, is defined as Julian-day - 2400000.5. See~\cite{MJD}. ! ! Note that d and d\_i8 are not valid for the No-Calendar. To remain ! consistent with non-Earth calendars added to ESMF in the future, ESMF ! requires a calendar to be planet-specific. Hence the No-Calendar does ! not know what a day is; it cannot assume an Earth day of 86400 seconds. ! ! Hours, minutes, seconds, and sub-seconds can be used with any calendar, ! since they are standardized units that are the same for any planet. ! ! Time manager represents and manipulates time internally with integers ! to maintain precision. Hence, user-specified floating point values are ! converted internally to integers. Sub-second values are represented ! internally with an integer numerator and denominator fraction (sN/sD). ! The smallest required resolution is nanoseconds (denominator), per Time ! Manager requirement TMG3.1. For example, pi can be represented as s=3, ! sN=141592654, sD=1000000000. However, via sN\_i8 and sD\_i8, larger ! values can be used. If specifying a constant floating point value, be ! sure to provide at least 16 digits to take full advantage of double ! precision, for example s\_r8=2.718281828459045d0 for 'e' seconds. ! !
