This sounds really cool. I have actually made something similar (unpublished and quite hacky though).
I work as a self-employed contractor and must report my times in varying standardised formats, depending on the client or agency I am working with. My input data comes from TimeWarrior (like yours) and I usually just output CSV data so I can copy-paste that into a provided excel template.
Quantizing the data is usually the most essential step as the templates often restrict accuracy. I find it strange that many of the comments here presume this kind of transformation to be fraudulent.
I have no idea what I'm talking about but could the angular sand extracted from rivers be replaced by round sand from the desert? Over time, that might be shaped into the way we like it, right?
Yeah, it sounds weird out-of-context but if you read the article, you'll get it.
