Usa std::literals para unidades de tiempo

Usa std::literals para especificar el tiempo con sufijos como muestra [aquí](https://en.cppreference.com/w/cpp/symbol_index/chrono_literals)

Search the C++ source for time values that are written without chrono literal suffixes, then consult the linked cppreference chrono_literals documentation. Update the applicable expressions to use std::literals and verify that the simulator still builds and its existing checks pass.
