From: Emanuele Ghidoli <[email protected]> There are two types of alarm tests: one that tests alarms on minute boundaries and another that tests alarms on second boundaries. For RTCs with one-minute resolution, only the minute boundary test should be run. Skip the second boundary alarm test for these RTCs.
