I have a photon that uses the ntp-time library. It compiled with firmware .6.0. Now I recompile the same sketch and I get a compile error:  
/workspace/ntp-time/ntp-time.h:19:3: error: ‘Timer’ does not name a type  
Timer\* timer;

Don’t know what has changed, My sketch didn’t.

I would double-check that your Photon is the selected device you’re targeting (with the gold star). If it becomes deselected, then builds generally default to Core, and Core doesn’t support software timers, causing the error above.

Ok, I actually had a pi selected, sorry.
