inTimeRange is a logic operator used to determine if a specific DateTime value falls between two other points in time.

• CLR Bound: By calling through to the Common Language Runtime (CLR), the operator ensures that time comparisons follow standard .NET rules, including handling of ticks and milliseconds.
• Result: It always returns a Boolean (true or false).

Syntax

self.[DateTimeProperty].TimeOfDay.inTimeRange(TimeSpan.FromHours(X), TimeSpan.FromHours(Y))

• TimeOfDay: Extracts the duration since midnight from the DateTime.
• TimeSpan.FromHours(n): A direct call to the .NET library to create a valid duration object for the range.

Example

-- Check if the Order time falls within the defined TimeSpan range
vResult := self.OrderDate.TimeOfDay.inTimeRange(TimeSpan.FromHours(0),TimeSpan.FromHours(0))

To avoid the common "Type Mismatch" error (where DateTime is compared to TimeSpan), the implementation follows three critical steps:

1. Value Extraction (.TimeOfDay):
   • This converts the full DateTime (e.g., 2026-03-09 14:30) into a TimeSpan (e.g., 14:30:00).
   • This ensures the comparison is day-independent.
2. Range Definition (TimeSpan.FromHours):
   • The start and end points are defined using direct CLR calls.
   • In the example above, using (0, 0) checks for the exact start of the day (Midnight).
3. Variable Assignment (vResult := ...):
   • The result is a Boolean (True or False).
   • The := operator assigns this result to a variable for use in subsequent logic or UI display.
