Yahoo ignores from dates and defaults to first record

[milktrader]

After some debugging it appears the issue with with Yahoo. The c field is for the from year value, but it's ignored.

julia> head(yahoo("GLD", 22,22,22,  1,21,2006, "d"))
6x7 DataFrame:
              Date  Open  High   Low Close      Vol   Adj

I should have checked this first, but this confirms that it's not the Yahoo api but the yahoo function that is bugged.

> getSymbols("GLD", from="2010-01-01")
    As of 0.4-0, ‘getSymbols’ uses env=parent.frame() by default.
 This behavior will be phased out in 0.5-0 when the call will check
 getOptions("getSymbols")$env for default value. If NULL, auto.assign will
 be set to FALSE.  This message is only shown once per session.

The api was defaulting to the first record because it was getting a bogus value for month.
