But how accurate is this device's timestamp? Even with NTP, there could be a lot of skew if it only syncs once in a while and has a bad internal clock otherwise

But how accurate is this device's timestamp? Even with NTP, there could be a lot of skew if it only syncs once in a while and has a bad internal clock otherwise.
The font of the timestamp/label is familiar though, so it's probably a cheap Chinese device, and I'd guess they're so widely used that they've managed to make the clock to be quite accurate.

If the camera is on the far-side of the transformer from the epicenter, then it could take from 5 to 30 or more seconds for ground shocks to be apparent. Speed of travel through solid rock is about 10,000 km/h, slower through softer or more disrupted geology.
