Current date and time as number of seconds/300
Note: Many $functions have been deprecated in favor of Object Oriented methods. There is currently no OO equivalent for the $Sir_DateN function.
The $Sir_DateN function has no arguments and returns the number of 1/300 second units since 1 January, 1900.
Syntax
%num = $Sir_DateN
Syntax terms
| %num | Set to the number of 1/300th seconds units from 1 Jan 1900 12:00 AM to the current date and time.
|
|---|
Usage notes
- $Sir_DateN has no error conditions.
- Values returned by $Sir_DateN will exceed the range that can be represented in a 4-byte integer, so you should probably avoid storing the value in a BINARY or FLOAT4 field.
- To obtain the current date and time in a readable form, use $Sir_Date.
- To convert a datetime number to a readable form, use $Sir_N2Date.
Example
The following fragment will print the date and time 1.5 seconds from the current time:
PRINT $Sir_N2Date($Sir_DateN + 450, 'MM/DD/YY HH:MI:SS.XX')
