how to search for time like in virtual farm and build it?

Could be in milliseconds or something similar. Use the float value type. You could also try finding the 'isBuilt'/'isBuilding' flag in games which tells the game whether or not you can build again, or whether the build progress is complete. That is usually a 1-byte value of 1 or 0 (boolean setting). Sometimes it can be 1 when done, and 0 when not, or vice-versa. Should work in games that only allow you to build one thing at once as the memory address tends to be the same each time.
