+Subject: [PATCH] Use %lld in printf for 64-bit time_t
+
+musl 1.2.0 switched to use 64-bit time_t everywhere, including 32-bit
+architectures, causing garbage values to be printed from ppswatch and
+ppstest.
+
+Use the correct format string for the affected printf statements and
+explicitly cast to long long to avoid potential compatibility issues
+with 32-bit glibc.
+
