Paolo wants to record times in an Excel workbook, but he needs the times to be precise, including hundredths of a second. What he would like is a format such as 1.41.73, meaning 1 minute, 41 seconds, and 73 hundredths.
This type of formatting can be easily applied to a cell in the following manner:
Figure 1. The Number tab of the Format Cells dialog box.
The format shows elapsed time, with hours, minutes, seconds, and hundredths of seconds. If you prefer, you can change what delimiters are used between each element of the time. For instance, if you want to use decimal points and drop off the hours, you can use the following format in step 4: mm.ss.00.
