Local-notifcation 'at' and 'every' fields used together

I want a daily reminder at a specific time.
I just need help with how to set the ‘at’ variable, should it be a Date format or Date(myfulldate).getTime()?

at the moment I have:

this.notificationTime = new Date();

this.notification = {id: 1, title: “Wake Up”, text: “Wake up bro”, every:“day”, at: this.notificationTime.getTime()};


did you manage to use ‘at’ and ‘every’ ?
