Fixed Depreciation date diff readable precision

[inietov]

Description

Working with dates is tricky, the correct date diff in the Asset's view is something like "2 years, 10 months, 10 days from now", but the function we are using from the Carbon library only reports back the year part. So I added a parameter to return a little more precise string.
