comment Is there a convenient way to sum TimeSeries objects in Mathematica?
You can also set the missing data method on the TimeSeries objects to None. Not sure if that will work, I don't have M in front of me to try it.

comment What is the purpose of Internal`LocalizedBlock?
@Mr.Wizard just a little tidbit, if I recall correctly this was added for the purpose of fitted models being able to work with subscripted variables so I think Dan is right on here.

comment Why does TimeSeriesShift is just adding a fixed number of days?
That's probably why TimeSeriesShift does what it does. Both TimeSeries and TemporalData require unique time stamps. Also many algorithms are particular About uniform vs irregular spacing which is only preserved by a uniform shift.

comment Periodogram for irregularly spaced data
@Verbeia you should definitely file a suggestion with WRI for Periodogram to take TemporalData (and TimeSeries). This was on my todo list before I left I just didn't get to it.

comment Why is my data 10 times slower than random data when doing matrix multiplication
Computing the following Tally[ByteCount /@ Flatten[tb]] shows that some of your numbers have different byte counts due to large exponents. I doubt the data can be packed.
