Update cron schedule

Since I seemed to messed up the fact that 4PM UTC of first day of month, would have been 12AM of SGT, next day, rather than on same day.

Placing at :20, so that it runs few minutes after committed, as a test if it works.

Anyways NEA doesn't update on midnight as seen yesterday so its probably better this way.
