6. The device of claim 5 further including a third opening formed in said housing near the bottom surface thereof between said first and second sets of openings and substantially along the the center line of said housing, said third opening alignable with an opening existing in the structure of a meter for securing said housing therein.

7. The device of claim 6 wherein said third opening is a set of openings including three holes with two of said holes adapted to engage locating pins on a central mounting post of the meter, and a third hole alignable with a threaded opening in said central mounting post.

8. The device of claims 5 or 7 wherein said first set of openings includes three holes, selected ones of which are alignable with a threaded opening formed in a first mounting post on one side of a meter.

9. The device of claim 8 wherein said second set of openings includes two holes, selected ones of which are alignable with a threaded opening formed in a second mounting post on the opposite side of the meter.

10. A device for recording time of energy use for use with electric meters having a rotatable disc, comprising:

a housing configured to fit within a meter beneath the disc and securable therein, said housing containing circuit means for recording time of energy use;

a first set of two openings formed in said housing at a first side and near the top surface thereof;

a second set of three openings formed in said housing at a second side and near the top surface thereof; and

selected openings of said first and second sets of openings alignable with threaded openings existing in mounting posts located at opposite sides of the meter for securing said housing thereto.

11. The device of claim 10 further including a third set of three openings formed in said housing between said first and second sets and substantially along a center line of said housing, one of said openings of said third set alignable with a threaded opening existing in a central mounting post of a meter for securing said housing therein and two of said openings of said third set adapted to engage locating pins on said central post.

12. The device of claim 10 wherein a first opening of said first set is located about 1.765 inches from a center line of said housing and a first opening of said second set is located about 1.750 inches from said center line.

13. The device of claim 12 wherein a second opening of said first set and a second opening of said second set are each located about 1.687 inches from said center line.

14. The device of claim 13 wherein a third opening of said second set is located about 1.275 inches from said center line.

15. A device for recording time of energy use for use with electric meters haivng a rotatable disc and a cup-shaped cover securable to a base to provide an enclosure, comprising:

a housing having front and rear faces, and configured to fit within the enclosure below the disc, said housing containing circuit means for recording time of energy use;

a first set of mounting openings formed at one side of said housing near the top thereof;

a second set of mounting openings formed at the opposite side of said housing near the top thereof;

selected ones of said first and second sets of mounting openings alignable with openings formed in a meter structure to secure said housing within the enclosure; and

a third set of mounting openings formed in said housing near the bottom thereof and between said first and second sets of mounting openings, at least one opening of said third set alignable with an opening formed in a meter structure for securing said housing within the enclosure.

16. The device of claim 15 wherein said third set of mounting openings is located within a recess formed in the rear face of said housing for receiving a central mounting post of a meter.
