suggest "alternate time" or "alternative time"

Hello,

Usually before setting up a meeting, I specify a time slot and ask others if they are fine with it. If not I ask them to suggest an alternate time.

e.g.
[
Shall we have our meeting tomorrow from 11:30AM to 1PM? If this time is not convenient to you, please suggest an alternate time.
]

But I have this confusion between "alternate time" and "alternative time".
I googled and found that both "alternate time" and "alternative time" seem to be in vogue. I would like to hear the opinion of the experts here.

Thanks,
Gopi

In both American and British English, the adjective 'alternate' means 'every other'
e.g. "There will be a dance on alternate Saturdays."

and the adjective 'alternativ'e means 'available as another choice' ( an alternative route;: alternative medicine; alternative energy sources, and in your example, 'please suggest an alternative time'.
