"""
|
||
|
|
a revset predicate for filtering by changeset age.
|
||
|
|
|
||
|
|
Adds the `age()` revset predicate.
|
||
|
|
|
||
|
|
This revset predicate differs from the built-in `date` by providing a more
|
||
|
|
granular way of considering relative time rather than absolute time.
|
||
|
|
|
||
|
|
The built-in `date()` predicate does provide full day resolution, so
|
||
|
|
`age("<Xd")` is equivalent to `date("-X")`.
