Function rdbLoadTime

app/redis-6.2.6/src/rdb.c:121–125

This is only used to load old databases stored with the RDB_OPCODE_EXPIRETIME * opcode. New versions of Redis store using the RDB_OPCODE_EXPIRETIME_MS * opcode. On error -1 is returned, however this could be a valid time, so * to check for loading errors the caller should call rioGetReadError() after * calling this function. */
