If your module has separate DS and SCLK pins (common on old DS1302 modules), do not use VirtuabotixRTC. That library is for I2C modules only (DS1307/3231). For DS1302, you need the DS1302 library. virtuabotixrtch arduino library

Unlike higher-abstraction libraries that hide register-level operations, VirtuabotixRTCH offers a transparent, function-rich API that feels like natural Arduino code. virtuabotixrtch arduino library
