Speeding up build time

okay so i found the address for the time left on building my volt warframe and i changed it however when i clicked claim it gave me an unknown error (when i logged back in the original timer was restored) any ideas on how i could make it let me claim?

That's just the visual... not the actual address.
You can do the same thing with a speedhack, it just doesn't let you claim because it's server sided.
