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')
