I need some tips on how to draw timing chart.

Hello fellows,
I need some tips on how to draw timing chart. Timing charts are composed with date, time and year this is often needed by a sales report or minutes for a specific agenda on some meetings. As a secretary in a small company I have to do my job and present a timing chart to my boss. I should ask some tips from you guys on how to get this done properly. Thanks.
Regards,
Rebecca Green.
