Ultimate GPS: What time is it when the PPS signal rises?

Post by gaperjeffey »

I'm building an application that synchronizes the time on my PC from the Ultimate GPS.

I plan to set the time from the Ultimate GPS when the PPS signal rises by hooking up the PPS signal to an interrupt and then sending the time to my PC in that interrupt. When the signal rises, is the time the time in the last NEMA sentence the Ultimate GPS sent or is it the next whole second of the last sentence? Thanks!
