navFormReceiveReadDateTime (Function)

This function will read the value of a date or time field on a received form.

Note that the received form is only valid after a "Form received" event is raised; the event will not be removed until the navFormReceiveDone function is called.

Input:

id : DINT (1..2147483647)

ID of the field to read.

Output:

linsec : DINT

The value of the field.

For time fields, this is the number of seconds since midnight on 1980-01-01.

Returns: INT
