# Revision history [back]

Let all to be affected calculations depend (directly or indirectly) on the cell in which the time is changed, i.e. add that cell's time or have the cell otherwise appear in the cells' formula expressions. Other than that, your question is unspecific and unclear.

Update from first comment:

• effective start time A1: =A2+A3
• regular start time A2: 10:00
• delay A3: 00:30
• interval A4: 01:00
• time slot B1: =A1
• time slot B2: =B1+A$4 • time slot B3: =B2+A$4
• ...

You can copy&paste or pull the formula down as desired.
