MATLAB C Coder exports times function which conflicts with MacOSX12 SDK's times function

When we export our MATLAB files to C, they export times.h which contains a function with the same name, called times. Therefore, when I attempt to compile the exported C code in my iPhone app using clang, the function conflicts with the macOS SDK version of times (see the log below). How can I avoid this conflict?
Thank you,
William

The configuration parameter ReservedNameArray in coder.EmbeddedCodeConfig object can be used to specify names that the code generator must not use for functions or variables, specified as a string arrays, cell array of character vectors, or character vector.
Also, if there are issues with a file named times.c/h, the configuration parameter CustomFileNameStr in coder.EmbeddedCodeConfig can be used to mangle generated file names.
