Time Warp

Hi, Looking at the history for N59TF, I see that it departed KPTW before it arrived from KRDU on 1/27/09. How is this possible?

Thanks for a great tool!

Raleigh-Durham Intl (KRDU) Pottstown Limerick (KPTW)
Departure: 06:44 CST Arrival: 07:32 CST Duration: 0:48

Pottstown Limerick (KPTW) Sheboygan County Memorial (KSBM)
Departure: 18:10 CST Arrival: 20:22 CST Duration: 2:12

Well, if I could tell the diff between am and pm, it would help. Thanks!
