To expand on @escada's answer, an example ruleset for Overpass would be:
----------
[out:json][timeout:25];
(
node(a,b,c,d)(newer:"2016-05-14T07:00:00Z");
);
out body;
>;
out skel qt;
----------
The above would return all nodes modified after 14th May 2016.
- replace 'node' with 'way' or 'relation' as required
- replace a,b,c,d with lat/lons corresponding with: a=latitude southwest, south, b=longitude southwest, west, c=latitude northeast, north, d=longitude northeast
east
The ruleset can be pasted into [https://overpass-turbo.eu/][1]
