instance method `max_mtime`

Ruby on Rails 7.2.3

Since v4.0.13 Private

Available in: v4.0.13 v4.1.16 v4.2.9 v5.2.8.1 v6.0.6 v6.1.7.10 v7.0.10 v7.1.6 v7.2.3 v8.0.4 v8.1.2

Compare with:

max_mtime(paths)

This method returns the maximum mtime of the files in paths, or nil if the array is empty.

Files with a mtime in the future are ignored. Such abnormal situation can happen for example if the user changes the clock by hand. It is healthy to consider this edge case because with mtimes in the future reloading is not triggered.

Parameters
