 ### By Snapshot ID
 
-Read data from a specific snapshot by passing an integer literal:
+Read data from a specific snapshot by passing an integer:
 
 ```sql
-SELECT * FROM paimon.default.my_table FOR SYSTEM_TIME AS OF 1
+SELECT * FROM paimon.default.my_table VERSION AS OF 1
 ```
 
-This sets the `scan.snapshot-id` option and reads exactly that snapshot.
+This sets the `scan.version` option. At scan time, the value is resolved as a snapshot ID.
 
-### By Timestamp
+### By Tag Name
 
-Read data as of a specific point in time by passing a timestamp string in `YYYY-MM-DD HH:MM:SS` format:
+Read data from a named tag. Since `VERSION AS OF` in SQL only accepts numeric values, tag-based time travel is done via the `scan.version` table option:
 
-```sql
-SELECT * FROM paimon.default.my_table FOR SYSTEM_TIME AS OF '2024-01-01 00:00:00'
+```rust
+let table = table.copy_with_options(HashMap::from([
+    ("scan.version".to_string(), "my_tag".to_string()),
+]));
 ```
 
-This finds the latest snapshot whose commit time is less than or equal to the given timestamp. The timestamp is interpreted in the local timezone.
+At scan time, the version value is resolved by first checking if a tag with that name exists, then trying to parse it as a snapshot ID. If neither matches, an error is returned.
 
-### By Tag Name

-Read data from a named tag by passing a string that is not a timestamp:
+Read data as of a specific point in time by passing a timestamp string in `YYYY-MM-DD HH:MM:SS` format:

 ```
 
-Tags are named snapshots created via Paimon's tag management (e.g., `CALL sys.create_tag(...)` in Spark). This is useful for pinning a stable version of the data for reproducible queries.

 ### Enabling Time Travel Syntax
