Hi @sweenig,

You're in luck! A bunch of community members ported Network Time syncing code to run on the core, and I recently made a blink an LED example using their code. I posted that here:

> I was totally serious, here’s a version that syncs the clock with an NTP server, and then blinks on 5 second intervals (code from this thread! https://community.spark.io/t/getting-utc-time-from-ntp-server/1213/3 - Thanks! ) UDP UDP; char string\[...

This program blinks on every multiple of 5 seconds synced with a time server, it should be a small step to port that to blink at 8am. 🙂

Thanks,  
David
