Too slow for Input Capture? 1Hz

Looking to measure duty cycle of a pin where I'm looking for a pulse anywhere between 200miliseconds and 800 miliseconds on a 1Hz period. I think I used the terminology correctly, sorry if I didn't. Much of the time, the pin could be ringing with a lot of noise, rather than a good solid pulse. It is a WWVB receiver/decoder.


It seems like the counters might be rolling over before my input period ends, so I would have to slow down the clocks. I think.


I could probably just use GPIO and external interrupts, and simply count ticks between them.


Your thoughts?
