Convert datetime number of seconds to string
Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is no OO equivalent for the $Sir_NS2Date function.
The $Sir_NS2Date function expects a numeric datetime argument containing a number of seconds 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_NS2Date accepts an optional error control string and returns the null string if an error is detected.
Syntax
<section begin="syntax" /> %dat = $Sir_NS2Date(datn, fmt, errctl) <section end="syntax" />
Syntax terms
%dat | Set to the datetime value string, using format specified by fmt/var>, corresponding to datn, unless an error is detected. |
---|---|
datn | Datetime number containing a signed number of seconds 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". |
Example
The following fragment prints the string 07/31/84:
%X = $Sir_Date2NS('8407301230', 'YYMMDDHHMI') * Add 15 hours: %X = %X + 60 * 60 * 15 PRINT $Sir_NS2Date(%X, 'MM/DD/YY')
Usage notes
- The inverse of this $function is $Sir_Date2NS.
- $Sir_NS2Date returns a null string in the following cases:
- fmt is not a valid datetime format.
- datn out of range.
