Can't seem to set a time other than on the hour

[jacinferreira]

Steps to Reproduce
0) Install callie add-on

1. @callie schedule: daily, event: Nehuen’s 30th Birthday, hour: 09:57
2. I've updated your countdown reminder for Nehuen’s 30th Birthday!

Expected Result
Callie to run event at 9:57am

Actual Result
Callie runs the event at 9:00am

Notes
I've tried formatting as 0957 also and I get an error:
Something went wrong with updating that countdown, sorry! Did you get the name of the event right?

@jacinferreira hi there! thanks for filing an issue on this - right now, callie only checks for automated reminders on the hour. i've been meaning to store minute info as well for quite some time but just haven't found the time to do it yet. this will bump it up on my to-do list though. if you're feeling frisky and want to give it a go yourself, this repo gladly accepts outside contributors as well!

I'll leave this open for now to remind me to take a look when i have some time soon.
