Start timestamp of next row is end timestamp of prev row

Hello Friends,

Am trying to generate a set of data for activities occuring in a specific order. Hoping to create about 100 rows or so…I have a start time-stamp and an end timestamp. For each row the start timestamp will the end timestamp of prev row. How to do…

Example: assumes starting point is 1/1/2019 15:00:00( can be any datetime )

Row 1: Watch Movie: starts at 1/1/2019 15:00:00 , ends at 1/1/2019 17:00:00
Row 2: Go to dinner: starts at 1/1/2019 17:00:00, ends at 1/1/2019 18:30:00
Row 3: Drive home: starts at 1/1/2019 18:30:00, ends at 1/1/2019 19:45:00

and so on…

MM
