How do you answer right now questions on WikiAnswers?

You could include a 'time stamp' in your answer - so the reader can see when it was written. A typical question I come across is "How much is 1,000 dollars in UK money" - Since currency prices fluctuate by the minute, I would normally answer 'At the time of writing (08:20 Sunday 19/02/2012) $1000 is worth approximately £631.35'
