The symbol GLD has options available to it. Option naming doesn't appear to be consistent. For example, for a 2012/02/10 expiry for a GLD call is 'GLD1210B167'. 120210 is a Friday. On the other hand, for GLD option dated 120518, the option actually has a Saturday date: 'GLD1219E86'. Is there a method to this madness? I see IB has similar dating, so I believe it is official, but why?

The confusion is understandable.
The GLC option that expires on Feb. 10 is a weekly option.
The GLC options that expire on 2-18, 3-17, 4-21, and 5-19 are the monthly options
and their expiration rule is: Saturday immediately following the third Friday of the expiration month.
Here is a CBOE web site that tells more:http://www.cboe.com/Products/OptionsOnETFs.aspx#etfspec
Thanks for the question.
