Something like this if possible?

Code:
2018-02-02 ./file1.jpg
2018-02-02 ./file2.jpg

Hmmm - my silver spoon for spoon feeding is in the dish washer momentarily. Quick, quick - let me dash out to get it for you ...
How about
Code:
find . -name "*.jpg" -printf "%TY-%Tm-%Td %p\n"

If you have a version of bash or ksh that groks the globstar option:

ksh:
Code:
$ set -o | grep glob
glob                     on
globstar                 off
$ set -o globstar
$ set -o | grep glob
glob                     on
globstar                 on

bash:
Code:
$ shopt | grep glob
dotglob        	off
extglob        	on
failglob       	off
globstar       	off
globasciiranges	off
nocaseglob     	off
nullglob       	off
$ shopt -s globstar
$ shopt | grep glob
dotglob        	off
extglob        	on
failglob       	off
globstar       	on
globasciiranges	off
nocaseglob     	off
nullglob       	off

You can use:
Code:
ls -rtd **/*.jpg

This will find all instances of *.jpg under the current working directory and list them as you required. Note that I used the -d option to ls just in case somebody named a directory with a .jpg suffix.

You mention wanting to search the whole file system. If your system has the locate, or newer mlocate package installed consider this:
Code:
locate -b -e -0 '*.jpg' | xargs -0 ls -rtd

This works for my Ubuntu 16.04 release with mlocate 0.26. The -b option forces it to check against the basename of each file; -e to ignore non-existent files (possible if you deleted files since the last update of the mlocate database, which is normally done once a day).

Note that if you're trying to get a single list of files sorted by timestamps, anything that feeds the list to be processed to xargs is not going to achieve your goal. By definition, xargs will split the unsorted list of files into multiple sublists to be processed by executions of the target utility (ls -rtd in this case) and, although each execution will give you an ordered list, the concatenated lists produced by those multiple executions will not give you a list that is sorted by the last modification timestamps of all of the files in the list.
