Detailed Description

The DecomposeTimestampOperator decomposes the input timestamp into date and time basic parts.

Arguments

When operator is used inside a signal its default input is automatically tied to signal's InternalValue or previous operator's output. Its default output is automatically tied to next operator's input or to signal's Value. See also CDP Operator Usage In CDP Signals.

Actual Processing Code of the DecomposeTimestampOperator

  int error;

    error = OSAPIGMTime(&t_tm, &t);
  else
