Example 2 
As the field definition for Timer::Reminder (a calculation field with five repetitions), calculates future times based on the contents of Timer::Start Time (a time field) and Timer::Snooze Minutes (a number field):
Time ( Hour ( Extend ( Timer::Start Time ) ) ; Minute ( Extend ( Timer::Start Time ) ) + ( Extend ( Timer::Snooze Minutes ) * Get ( CalculationRepetitionNumber ) ) ; Seconds ( Extend ( Timer::Start Time ) ) )
Note  The Extend function allows a non-repeating field to be used in every repetition of a repeating field.
When Timer::Start Time contains "12:00:00" and Timer::Snooze Minutes contains "6":
