TestCase date format seems to be fixed to US style

HI,

If a test is marked up with

[TestCase("7/10/13 13:16")]
public void DeductionsShouldBeWithinTimeUsed(DateTime deductionStart)

And the test is run in using Resharper, then the date is interpreted as 10 July, whereas being in the UK I would want 7 October.  Can you add an option to set the parsing locale?
