You can use the find command and specify a time range. In your example: if you want to find all files with the changed timestamp from January 6, 17:28, you can do something like:
find . -type f -newermt '2016-01-06 17:28' ! -newermt '2016-01-06 17:29'
, exec exec:
find . -type f -newermt '2016-01-06 17:28' ! -newermt '2016-01-06 17:29' -exec rm {} \;
-name '*.txt', *.txt maxdepth,
