Claims
- 1. A time conversion device comprising, in combination:a body section having a table of time zones printed thereon wherein the body section is a writing instrument; a tubular sleeve that fits over the body section wherein the tubular sleeve has a fixed portion which displays a local 12 hour column and a window which shows the corresponding time zones as printed on the body section; a fastening device coupled to the tubular sleeve for rotatably coupling the tubular sleeve to the body section; and a cap removably coupled to the body section for protecting the writing instrument from the environment.
- 2. A time conversion device in accordance with claim 1 wherein the fixed portion of the tubular sleeve further displays a local 24 hour column.
- 3. The time conversion device of claim 1 wherein the fastening device comprises:a holder coupled to one end of the body section; a knob coupled to the tubular sleeve; and a drive pin for rotatably coupling the knob to the body section.
- 4. The time conversion device of claim 1 wherein the body section is a highlight marker.
- 5. The time conversion device of claim 1 wherein the tubular sleeve is made of a poly carbonate material.
- 6. A time conversion device comprising, in combination:a body section having a table of time zones printed thereon wherein the body section is a writing instrument; a tubular sleeve that fits over the body section wherein the tubular sleeve has a fixed portion which displays a local 12 hour column and a local 24 hour column and a window next to the fixed portion which shows the corresponding time zones as printed on the body section; a fastening device coupled to the tubular sleeve for rotatably coupling the tubular sleeve to the body section wherein the fastening device comprises: a holder coupled to one end of the body section; a knob coupled to the tubular sleeve; and a drive pin for rotatably coupling the knob to the body section; and a cap removably coupled to the body section for protecting the writing instrument from the environment.
- 7. The time conversion device of claim 6 wherein the body section is a highlight marker.
- 8. The time conversion device of claim 6 wherein the tubular sleeve is made of a poly carbonate material.
- 9. A method of providing a time conversion device comprising the steps of:providing a body section having a table of time zones printed thereon wherein the body section is a writing instrument; providing a tubular sleeve that fits over the body section wherein the tubular sleeve has a fixed portion which displays a local 12 hour column and a window which shows the corresponding time zones as printed on the body section; providing a fastening device coupled to the tubular sleeve for rotatably coupling the tubular sleeve to the body section; and providing a cap removably coupled to the body section for protecting the writing instrument from the environment.
- 10. The method of claim 9 further comprising the step of providing a fixed portion wherein the fixed portion of the tubular sleeve further displays a local 24 hour column.
- 11. The method of claim 9 wherein the step of providing a fastening device further comprises the steps of:providing a holder coupled to one end of the body section; providing a knob coupled to the tubular sleeve; and providing a drive pin for rotatably coupling the knob to the body section.
- 12. The method of claim 9 wherein the step of providing a tubular sleeve further comprises the step of providing a tubular sleeve made of a poly carbonate material.
