Hi Rick,
For some reason Ibex saves the reception time in seconds, while PennController saves event times in milliseconds. You can take look up the participant’s first row, take the Event Time and subtract it from the Reception Time (times 1000) and you’ll get a proxy for the duration in milliseconds
