Can I specify the time when proposals are due?

Yes. You can specify the exact time when proposals are due. 

When scoping your requirements, Glo prompts you to set a specific time and time zone for the proposal due date. This functionality gives you granular control over when you want suppliers to submit proposals for your projects and provides additional clarity for business users and suppliers.  

If the time or time zone is not selected, the default is set to 11:59 PM in your current time zone. Additionally, invited suppliers receive briefs with the due dates and times automatically shown in their time zones.
