Revision history [back]

I sum up times and the sum goes beyond 24h and need to multiply the hours with an hourly rate to create an invoice.

• Until 23:59 I can use the formula =(HOUR(G15)+MINUTE(G15)/60)*320 to linearize the time
• Beyond 23:59 the used formula reduces the time value by 24h. This is the correct functionality of the HOUR(cell) function.

I searched Help and Help Wiki but it seems that I overlooked the solution.

I appreciate any help which helps me to linearize hours and minutes beyond 23:59.
