+  * YAM_COs.c: Initialize co->BirthdayCheckTime.ds_Days before calling
+    String2DateStamp() or DateStamp2String() because otherwise the functions
+    return unexpected results. This closes #145.
+  * YAM_AB.c: Do the birthday compare only if here is really anthing to compare.
+    Use the saved BirthdayCheckTime seconds (ticks) for the next check too.
