more printing fixes:
1. the last commit to determine the timeline fontsize was wrong. the better solution is to use the cell width
2. draw a complete horizontal line in the timeline box under the text when using the pH:MM AMPM time format
3. use an incredibly tiny 6pt helvetica font to display the small month box in the header as necessary dependent on the height of the header.

what's better? a tiny font or a slightly bigger font that's mashed together with other date numbers? neither is especially readable.
