replace them.

+Subject: [PATCH] isp-imx: drop use of __TIME__, __DATE__
+
+With reproducible build enabled the compiler is configured to throw
+an error if __TIME__, __DATE__ preprocessor macros are used.
+
+| isp-imx-4.2.2.11.0/mediacontrol/daemon/main_v4l2.cpp:99:44: error: macro "__DATE__" might prevent reproducible builds [-Werror=date-time]
+|    99 |              std::cout << "Build Time : "<<__DATE__<<", "<<__TIME__<<std::endl;
+|       |                                            ^~~~~~~~
+
+Fix this by replacing __DATE__, __TIME__ with BUILD_DATE and setting
+BUILD_DATE from CMakeLists.txt to either SOURCE_DATE_EPOCH if present
+or the local time otherwise.
