The previous bound (~year 2262) was too permissive: paths that add an offset to the mocked time (e.g. the future-time check in ContextualCheckBlockHeader) can overflow int64_t (caught by UBSan), and paths that assign it to a uint32_t field (e.g. pblock->nTime in miner.cpp) silently truncate it (caught by the integer sanitizer). UINT32_MAX is the natural ceiling since block header nTime is uint32_t, and mocking beyond it is meaningless for anything consensus-related. Add setmocktime bound checks to the existing _test_y2106 case in rpc_blockchain.py, and remove the negative bound check from rpc_uptime.py.
