How to convert a md5sum back to a timestamp?

[Peng Yu]

Hi,

Suppose that I know a md5sum that is derived one of the timestamps
computed below. Is there a way to quickly derive what the original
timestamp is? I could make a database of all the timestamps and their
md5sums. But as the total number of entries increases, this solution
will not be scalable as the database can be big. Is it there any
better solution to this problem?

for i in {1..2563200}; do date -d "-$i minutes" +%Y%m%d_%I%M%p; done
