Perhaps one way ..
Assuming the sample data:
5/7/04 16:03 Jon Smith
5/10/04 9:02 Raul
5/10/04 15:59 Joe Bloke
5/11/04 8:57 Ben Over
5/11/04 15:59 Smiley Face
5/12/04 9:06 Ronaldo
5/12/04 15:59 Shaft
5/13/04 9:27 Lorna
5/13/04 16:12 RVN
5/14/04 8:19 Roger
is in A1:A10
Let's split the data first
Select col A
Click Data > Text to columns
("Delimited" will be selected)
Click Next
In step2 of the wiz.:
Check the box for "space" > click Next
In step3 of wiz.:
In the data preview pane: click to select the first col (the dates col)
Select "MDY" from the drop menu under "Col data format"
Click Finish
The original data in col A will be split
into 4 cols, A to D: Date, Time, Name1 & Name2
Now to apply the cond format:
Select A1
10
(i.e. the entire sample data range)
Click Format > Conditional Formatting
Under Condition 1, make the settings:
Formula Is | =$B1>TIMEVALUE("9:00 AM")
Click Format button > Patterns tab > Light blue? > OK
Click OK at the main dialog
The above should accomplish what you want:
