I want to convince the architecture manager to include the joda time jar in our product. Do you know any disadvantages in using it?

All the date manipulati...
Hi, I would like to find out the date of the Monday in this year's ISO week 1 (For 2009 this would be Monday, Dec 29 2008). I'm sure that joda-time can handle this, but I just can't figure out the API (maybe it's just too late). Can anyone help? Thanks! ...

I'm using the Joda-Time library with Java. I'm having some difficulty trying to turn a Period object to a string in the format of "x days, x hours, x minutes".
