+> ```python
+> s = "ANDROMEDA"
+> s[0:3]   # "AND"
+> s[3:7]   # "ROME"
+> s[-2:]   # "DA"
+> ```

+> Implement `extract(header)` that returns a tuple `(date, time)`:
+>
+> - `date` = `YYYY-MM-DD` (10 chars)
+> - `time` = `HH:MM:SS` (8 chars)
+>
+> Figure out which slice positions hold each piece.

+
+## Your Task
+
+In `starter/starter.py`, return `(date, time)` extracted with slicing.
+
+## Objectives
+
+- `extract("TIMESTAMP=2026-05-04T14:32:01Z")` → `("2026-05-04", "14:32:01")`
+- Works for any header in the same fixed format
