Review Comment:
```suggestion
String oldJson =
fileIO.readFileUtf8(snapshotManager.snapshotPath(snapshotId));
ObjectNode node = (ObjectNode)
JsonSerdeUtil.OBJECT_MAPPER_INSTANCE.readTree(oldJson);
node.put(Snapshot.FIELD_TIME_MILLIS, newTimeMillis);
String newJson =
JsonSerdeUtil.OBJECT_MAPPER_INSTANCE.writeValueAsString(node);
fileIO.overwriteFileUtf8(snapshotManager.snapshotPath(snapshotId),
newJson);
