Pipes for data display?

I have a use case, where I have a table of issues and the period of time they took to be resolved. The time they take to be resolved varies from several minutes, to several days. So I use a [MomentJS Pipe](https://github.com/urish/angular2-moment) to parse the times into a human readable form, e.g. `2 hours` or `14 minutes`. However, this poses an error with table sorting, as 14 is bigger than 2, so it gets put above it in the table.

I believe the ideal solution is to be able to leave the data in its raw form before it's passed to the table and then specify a display pipe which the module can apply after sort (but before search?)?

What do you think?
