I am getting this error when I try to compile a freshly cloned repository:

Error: Truffle is currently using solc 0.5.16, but one or more of your contracts specify "pragma solidity ^0.4.18".
I changed the versions in the files but it still throws errors for the zepplin-safemath.sol etc imported contracts.

Before this there was also a problem with running npm install on the repo.

TypeError: '>=' not supported between instances of 'tuple' and 'str'
gyp ERR! configure error 
gyp ERR! stack Error: `gyp` failed with exit code: 1

Did you have any issues deploying to truffle? When I do:

truffle compile truffle migrate

I keep getting this error:

Deploying ZombieOwnership... Error encountered, bailing. Network state unknown. Review successful transactions manually. Error: The contract code couldn't be stored, please check your gas amount.

I've tried upping the gas on the ZombieOwnership in the migrations tab but can't get it working

You've said that we will have a problem with the overflow in 2038 since everyone is declaring timestamps as 32 bytes integers but if we calculate 2^32 -1 = 4,294,967,295 which is the max integer represented on 32 bytes, this number represents in Unix Timestamp Feb 07 2106 and not year 2038, so the overflow will happen on February 2106.
