Generate and return the current or the requested date and time as an integer-valued array of size 8 or a formatted string.
More...
Generate and return the current or the requested date and time as an integer-valued array of size 8 or a formatted string.
This generic interface performs and exceeds the functionalities of the well-known strftime() and strptime() in the C family of programming languages.
- When no input argument is provided, the procedures under this generic interface return the current date and time as an
integer vector of values of size 8, similar to the values argument of the Fortran intrinsic procedure date_and_time().
- When the
format argument is present, the procedures under this generic interface return the current date and time as a string with the specified format.
- When any components of the date and time are specified as input argument,
- if
format is missing, the procedures under this generic interface return the requested date and time as an integer vector of values of size 8 whose elements are set to the corresponding specified arguments and all other elements corresponding to the missing arguments are set to zero.
- if
format is present, the procedures under this generic interface return the requested date and time as a formated string.
The following specifier are recognized in the input format argument:
(Except where mentioned, the convensions are identical to those of the format argument in the strftime() function of the C/C++ programming languages)
(The specifiers marked with an asterisk (*) are locale-dependent in C/C++ but not currently in this library.)
| Specifier | Example | Description |
| \(\ms{%a}\) | Thu | Abbreviated weekday name * |
| \(\ms{%A}\) | Thursday | Full weekday name * |
| \(\ms{%b}\) | Aug | Abbreviated month name * |
| \(\ms{%B}\) | August | Full month name * |
| \(\ms{%c}\) | Thu Aug 23 14:55:02 2001 | Date and time representation * |
| \(\ms{%C}\) | 20 | Year divided by 100 and floored to integer (-2,147,483,647 to +2,147,483,647) (extends the C/C++ strftime behavior) |
| \(\ms{%d}\) | 23 | Day of the month, zero-padded (01-31) |
| \(\ms{%D}\) | 08/23/01 | Short MM/DD/YY date, equivalent to \(\ms{%m/%d/%y}\) |
| \(\ms{%e}\) | 23 | Day of the month, space-padded ( 1-31) |
| \(\ms{%F}\) | 2001-08-23 | Short YYYY-MM-DD date, equivalent to \(\ms{%Y-%m-%d}\) |
| \(\ms{%f}\) | 037 | The millisecond padded with leading zeros (unique to this library, follows the convension of Python for microsecond). |
| \(\ms{%g}\) | 01 | Week-based year, last two digits (00-99) |
| \(\ms{%G}\) | 2001 | Week-based year |
| \(\ms{%h}\) | Aug | Abbreviated month name * (same as \(\ms{%b}\)) |
| \(\ms{%H}\) | 14 | Hour in 24h format (00-23) |
| \(\ms{%I}\) | 02 | Hour in 12h format (01-12) |
| \(\ms{%j}\) | 235 | Day of the year (001-366) |
| \(\ms{%m}\) | 08 | Month as a decimal number (01-12) |
| \(\ms{%M}\) | 55 | Minute (00-59) |
| \(\ms{%n}\) | \(\ms{\n}\) | New-line character |
| \(\ms{%p}\) | PM | AM or PM designation |
| \(\ms{%r}\) | 02:55:02 pm | 12-hour clock time * |
| \(\ms{%R}\) | 14:55 | 24-hour HH:MM time, equivalent to \(\ms{%H:%M}\) |
| \(\ms{%S}\) | 02 | Second (00-59) |
| \(\ms{%t}\) | \(\ms{\t}\) | Horizontal-tab character |
| \(\ms{%T}\) | 14:55:02 | ISO 8601 time format (HH:MM:SS), equivalent to \(\ms{%H:%M:%S}\) |
| \(\ms{%u}\) | 4 | ISO 8601 weekday as number with Monday as 1 (1-7) |
| \(\ms{%U}\) | 33 | Week number with the first Sunday as the first day of week one (00-53) (currently not implemented) |
| \(\ms{%V}\) | 34 | ISO 8601 week number (01-53) |
| \(\ms{%w}\) | 4 | Weekday as a decimal number with Sunday as 0 (0-6) |
| \(\ms{%W}\) | 34 | Week number with the first Monday as the first day of week one (00-53) (currently not implemented) |
| \(\ms{%x}\) | 08/23/01 | Date representation * |
| \(\ms{%X}\) | 14:55:02 | Time representation * |
| \(\ms{%y}\) | 01 | Year, last two digits (00-99) |
| \(\ms{%Y}\) | 2001 | Year |
| \(\ms{%z}\) | +0100 | ISO 8601 offset from UTC in time zone in units of minutes (as returned by the Fortran intrinsic date_and_time()). |
| \(\ms{%Z}\) | CDT | Time zone abbreviation (daylight saving not implemented; different from the C/C++ strftime behavior which uses system time zone name) |
| \(\ms{%%}\) | % | A % sign |
- Parameters
-
| [in] | format | : The input scalar or array of the same shape as other array-like arguments of type character of default kind SK, containing the output format of the specified date and time (See the table above for a list of possible specifiers). (optional. If missing, the output date and time will be an integer vector of size 8.) |
| [in] | julianDay | : The input scalar of type real of default kind RK, containing the Julian Day to be converted to the corresponding Gregorian date and time.
(optional, default = it can be present only if all arguments are missing or if only format and/or zone are present.) |
| [in] | year | : The input scalar of type integer of default kind IK, containing the year of the Gregorian calendar.
(optional, default = the current value if all arguments are missing or only format is present.) |
| [in] | month | : The input scalar of type integer of default kind IK, containing the month of the year of the Gregorian calendar.
(optional, default = 1 or the current value if all arguments are missing or only format is present. It can be present only if year is present.) |
| [in] | day | : The input scalar of type integer of default kind IK, containing the day of the month of the year of the Gregorian calendar.
(optional, default = 1 or the current value if all arguments are missing or only format is present. It can be present only if month is present.) |
| [in] | zone | : The input scalar of type integer of default kind IK, containing the time zone of the Gregorian calendar in minutes.
(optional, default = 0 (UTC) or the current value if all arguments are missing or only format is present. It can be present only if either day or julianDay (but noth both) is present.) |
| [in] | hour | : The input scalar of type integer of default kind IK, containing the hour of the day of the Gregorian calendar.
(optional, default = 0 or the current value if all arguments are missing or only format is present. It can be present only if zone is present.) |
| [in] | minute | : The input scalar of type integer of default kind IK, containing the minute of the hour of the day of the Gregorian calendar.

| [in] | second | : The input scalar of type integer of default kind IK, containing the second of the minute of the hour of the day of the Gregorian calendar.
(optional, default = 0 or the current value if all arguments are missing or only format is present. It can be present only if minute is present.) |
| [in] | millisecond | : The input scalar of type integer of default kind IK, containing the millisecond of the second of the minute of the hour of the day of the Gregorian calendar.

- Warning
- The condition
0 < size(values) must hold for the corresponding input arguments.
The condition 9 > size(values) must hold for the corresponding input arguments.
The specified number of elements of values, if less than 8, must be consistent with the specifiers in input format.
For example, when \(\ms{%Z}\) is specified together with values, then the size of values must be at least 4.
An input argument year = 0 corresponds to the historic 1 BC notation of the Gregorian calendar.
This is in accordance with the convention in astronomical year numbering and the international standard date system, ISO 8601.
The input month must be a number between 1 and 12.
The input day must be a number between 1 and 31 and be consistent with the specified month and (leap) year.
The input zone must be a valid time zone in units of minutes.
The input hour must be a number between 0 and 23.
The input minute must be a number between 0 and 59.
The input second must be a number between 0 and 59.
The input millisecond must be a number between 0 and 999.
These conditions are verified only if the library is built with the preprocessor macro CHECK_ENABLED=1.
-
The
pure procedure(s) documented herein become impure when the ParaMonte library is compiled with preprocessor macro CHECK_ENABLED=1.
By default, these procedures are pure in release build and impure in debug and testing builds.

- Test:
- test_pm_dateTime
- Todo:
- Low Priority: Locale-dependent date and time formats can be added to this generic interface in the future, depending on the demand.
- Todo:
- Normal Priority: This interface can be extended to add
format input argument to all possible calling interfaces.
- Todo:
- High Priority: The format specifiers \(\ms{%U}\) and \(\ms{%W}\) must be implemented.
