The massive numbers make me think that the value is actually an encrypted value (with XOR encryption). My method for editing encrypted values isn't the most efficent one, but it works for me so I never bothered to learn another method.
The "1091707066" value should have a similar number 2 addresses below it, which is the encryption key. It would also have a value 2 above it which would be something similar to "273600". The "1091707066" value would be the bottom XOR encryption applied to the top "273600" value.
If we knew that the timer you are looking for is encrypted, there is a method specifically for finding encrypted values, but I've never used it before so don't know how to do it.
