OBT (I'm guessing onboard time actually), is probably using GPS time (https://en.wikipedia.org/wiki/Global_Positioning_System#Timekeeping https://en.wikipedia.org/wiki/Global_Positioning_System#Time...) which is now 18 seconds ahead of UTC due to additional leap seconds inserted into UTC since GPS time started.
