# Overview This test application is a direct translation of xtimer_msg to the ztimer API. It is meant mostly as a means to do size comparisons, thus tries to be as close as possible to the original. One notable change is the option to choose a different ztimer clock. By default, the test will use ZTIMER_USEC, unless ZTIMER_MSEC is compiled in, which will be used in that case.
