Hi,
In the settings of the plugin, you have a setting "frequency" to configure the number of seconds between each run. I suppose that you have the number of seconds in one day in there.
But you also have a setting "last update". This setting contains the date of the last time the plugin run in the past.
The date there is using the "unix timestamp" format which is the number of seconds from 1st of january 1970.
So, check the value you have in that setting. If you want the plugin to run 10 hours earlier, then substract 36000 (36000 is the number of seconds in 10 hours) to that setting value and save the plugin. This way, instead of running at 11:37 tomorrow, it will run at 1:37
