The following command will search for files in the current directory (.) that have in their name the colon character :.
The files that match will then be renamed and all instances of the colon character : in the names will be replaced by the full stop character ..
find . -name "*:*" -execdir sh -c 'mv "$1" "${1//:/.}"' _ {} \;
-execdir command {} +is like-exec, but the specified command is run from the subdirectory containing the matched file, which is not normally the directory in which you started find.
Example: if you have a file named 2017-03-15 14:34:44.116002523.png then it will be renamed to 2017-03-15 14.34.44.116002523.png.
