DATE = "15 Jun 2015 10:10:10"; date -d"$DATE" +%Y%m%d%H%M%S

Output :-

20150615101010

More on Dates
Note this only works on GNU date.
I have read that:

Solaris version of date, which is unable to support -d can be resolve with replacing sunfreeware.com version of date.

Update:-
Use ls command to find all files and use grep command for all files. 

ls | grep "[0-9]{14}"

grep command also accepts regular expression.
But it won't validate your file accurate. For example, if a file name is 20151835101010, then it will validate this file. But actually month and date both are wrong.
So my suggestion is to write a shell script to identify valid file name and find oldest of them by processing one by one.
