This update enhances flexibility in configuration management.

To the code, a flag we add,
For the Delta time, no longer sad.
Override it with care, set it just right,
Now the fork's timestamp shines so bright. 🌟

op-node/flags/flags.go (2)

• 268-273: The addition of DeltaOverrideFlag is consistent with the PR objective and follows the established pattern for optional flags. Ensure that automated tests are in place to verify the functionality of this new flag.

• 317-320: The DeltaOverrideFlag is correctly added to the optionalFlags slice, which is then included in the global Flags slice to be used by the CLI.

op-node/service.go (2)

• 206-212: The implementation of the DeltaOverrideFlag correctly checks if the flag is set and then assigns the provided value to config.DeltaTime. This matches the PR objective and the summary provided.

• 228-234: Similarly, the DeltaOverrideFlag is correctly implemented in the second hunk, where the value is assigned to rollupConfig.DeltaTime if the flag is set. This is consistent with the PR objective and the summary.
