+## Extra: Update Daily Events and Berries Still Grow When Playing without a RTC
+**Goal:** Make it so we grow the berries and update daily events by a set amountevery time we load the game if there is an RTC failure.
+
+In `clock.c` add the folowing function at the bottom.:
+```diff
+void FastForwardTime(s16 daysToUpdateDay, s16 hoursToGrowBerries){
+// Runs the UpdatePerDay function as if daysToUpdateDay days have passed and grows the berries by hoursToGrowBerries
+        s16 daysBerry = hoursToGrowBerries / 24;
+        s8 hoursBerry = hoursToGrowBerries % 24;
+        struct Time localTimeOffset;
+        localTimeOffset.days = *GetVarPointer(VAR_DAYS) + daysToUpdateDay;
+        UpdatePerDay(&localTimeOffset);
+        localTimeOffset = gSaveBlock2Ptr->lastBerryTreeUpdate;
+        localTimeOffset.days += daysBerry;
+        localTimeOffset.hours += hoursBerry;
+        UpdatePerMinute(&localTimeOffset);
+}
+```
+
+In `clock.h`:
+```diff
+void DoTimeBasedEvents(void);
++void FastForwardTime(s16, s16);
+```
+
+Finally, back in `main_menu.c`:
+```diff
+static void Task_MainMenuCheckBattery(u8 taskId)
+{
+    if (!gPaletteFade.active)
+    {
+        SetGpuReg(REG_OFFSET_WIN0H, 0);
+        SetGpuReg(REG_OFFSET_WIN0V, 0);
+        SetGpuReg(REG_OFFSET_WININ, WININ_WIN0_BG0 | WININ_WIN0_OBJ);
+        SetGpuReg(REG_OFFSET_WINOUT, WINOUT_WIN01_BG0 | WINOUT_WIN01_OBJ | WINOUT_WIN01_CLR);
+        SetGpuReg(REG_OFFSET_BLDCNT, BLDCNT_EFFECT_DARKEN | BLDCNT_TGT1_BG0);
+        SetGpuReg(REG_OFFSET_BLDALPHA, 0);
+        SetGpuReg(REG_OFFSET_BLDY, 7);
++       if (RtcGetErrorStatus() & RTC_ERR_FLAG_MASK)
++           FastForwardTime(2, 4);
+        gTasks[taskId].func = Task_DisplayMainMenu;
+    }
+}
+```
+In the example above, we'll grow the berries by 4 hours and update daily events as if 2 days have passed every time we load the game.
