A wait duration for a timer action element of a design-time flow plan is set. The wait duration being set relative to a specified data point of a table associated with the design-time flow plan. An operation associated with the timer action element executes at run-time to pause a flow for the wait duration prior to execution of an operation associated with an action element that is set to execute subsequent to the timer action element in the design-time flow plan. A specified timeframe for the timer action element of the design-time flow plan is set. The operation associated with the timer action element to pause the flow for the specified wait duration executes at run-time during the set specified timeframe. A natural language annotation associated with the timer action element of the design-time flow plan is displayed. The annotation presents the set duration and timeframe in a human-readable format.
