Add "ULL" to the 1000 as well to also force cast there. This is also done in the millis() function as seen here.

The 1000ULL added. Prior change (the uint64_t cast) reverted as redundant. Tested: Ticker used to fire after 900+ seconds, now it hasn't fired for 1342s, and counting.

Long duration was truncated when calculating milliseconds * 1000. ESP32 only: functions esp_timer_start_* require microseconds as uint64_t. ESP8266 is not affected as it uses a different API.
