ESP 32 cam, deep sleep wake up every 24 hours, or every week.

I would like ESP32 cam to wake up one time per day, or one time per week. How can I do that?
I follow wake up timer example, and it works up until around 3600 sec, it start to keep waking up every 1 sec.
I don’t know why? Perhaps the number is too large for esp_sleep_enable_timer_wakeup function?
 
esp_err_tesp_sleep_enable_timer_wakeup(uint64_t time_in_us)
https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/sleep_modes.html
 
I check this web site, uint64 should give really really large number. but why I can’t even wakeup
every 3600 sec?
