Hmm...
Would need to know the appropriate conversion rate. the 2 obvious
dates/times, on entry and now, may neither be the one wanted.
Also, often the buy/sell conversion rates are not the same!
Am sure there also other issues.
I don't think automatic conversion is as easy as you make it out to be.
