 Relative formats:
-- `<number>d` — days ago
-- `<number>h` — hours ago
+- `<number>s` — seconds ago
 - `<number>m` — minutes ago
+- `<number>h` — hours ago
+- `<number>d` — days ago
+- `<number>w` — weeks ago
+- `<number>mo` — months ago (30 days)
+- `<number>y` — years ago (365 days)
 - `now` — current timestamp
 
 Clients MUST evaluate relative timestamps at execution time, not at event creation.
