Something else for you to look at and maybe use...
Time Log
This is a PDF page which breaks up a normal working day (0800-1800) into 15 minute periods so that you can track how you spend your time.
Each 15 minutes has been given two lines so you can even break that down that period into even smaller chunks.
It has a column for diary reminders, another for phone calls and emails and whether they are being received or sent with space for comments on the subject matter. It all makes it easier to track how your time is spent on a daily basis.
In addition there's a column for smileys so you can see at a glance how your day went. If you pick up that mornings are going badly you can take action into changing what happens at those times.
I've had some good feedback from others that have used it but I'd like to hear from you guys too.
