$Sir_N2Date
Convert datetime number of seconds/300 to string
Note: Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is currently no OO equivalent for the $Sir_N2Date function.
The $Sir_N2Date function expects a numeric datetime argument containing a number of seconds/300 since January 1, 1900, and a datetime format string. It returns the date represented by the first argument, in the format corresponding to the second argument. $Sir_N2Date accepts an optional error control string and returns the null string if an error is detected.
Syntax
%dat = $Sir_N2Date(datn, fmt, errctl)
Syntax terms
| %dat | Set to the datetime value string, using format specified by fmt, corresponding to datn, unless an error is detected. |
|---|---|
| datn | Datetime number containing a signed number of seconds/300 since January 1, 1900. |
| fmt | Datetime format string. Refer to "Datetime string formats" for an explanation of valid datetime formats and valid datetime values. |
| errctl | Optional error control string; refer to "Datetime error handling". |
Usage notes
- The inverse of this $function is $Sir_Date2N.
- $Sir_N2Date returns a null string in the following cases (see the discussion in "Datetime error handling"):
- fmt is not a valid datetime format.
- datn out of range.
Example
The following fragment prints the string 07/31/84:
%x = $Sir_Date2N('8407301230', 'YYMMDDHHMI') * Add 15 hours: %x = %x + 300 * 60 * 60 * 15 Print $Sir_N2Date(%X, 'MM/DD/YY')
