 24. The 825 Gen2 defaults to 12 hour time which requires AM/PM labels to show the date/time. Legacy 825 indicators defaulted to 24 hour time. Many legacy apps do not allow for enough space to display the AM/PM labels. So slight modification of the date/time display code may be needed to accommodate 12 hour time.
+{{{#!c++
+void ShowDateTime(void)
+{
+        SetBkColor(COLOR_ATTENTION);
+        SetCurColor(nColorBlack);
+#if ARM64
+        char dt[32];
+        GetDateTimeStr(dt, 1);
+        // Use strlen to allow for 12 hour time am/pm indication
+        DisplayText(DSP_WIDTH_LEGACY - ((strlen(dt) + 1) * FONT_WIDTH), DATE_Y, dt);
+#else
+        DisplayText(DATE_X, DATE_Y, GetDateStr());
+        DisplayText(TIME_X, TIME_Y, GetTimeStr(1)); // Parameter 1 = Include seconds
+#endif
+        SetBkColor(nColorBlack);
+}

 25. Also (probably rare) if the app communicates with another system by serial port, network, or file import/export that interprets the data content as binary integers, floats, etc... it may be necessary to make changes to account for different [https://en.wikipedia.org/wiki/Endianness endianness]. The 825 Gen2 is ARM-64 little-endian, The Legacy 825 is Coldfire big-endian.
