How much does time matter?

I just started Wellbutrin today. On work days (Monday to Friday) I always take my meds around 6am (I'm on a couple other meds) but on weekends I sometimes get to sleep in and take them around 9-930am. Do you think this will be an issue with this medication? I've tried bringing my meds to work with me but sometimes that makes me forget to take them and honestly is just more inconvenient than taking them first thing in the morning. Obviously, my mental health is important and if taking them at the same time every day is more beneficial, I'd deal with the inconvenience.
