Request data from IB

[UniversalGoldmine]

This function requests 5 min data up until Date & Time: 20091123 18:00:00

Tws1.reqHistoricalData(1, "MSFT", "STK", "", 0, "","", "smart", "usd",0, "20091123 18:00:00","3600 S", "5 mins", "MIDPOINT", 1, 1);

I wonder if there is any function that do the opposite and requests data from:
20091123 18:00:00 until current time ?
