If you want your users to be able to select start and end times, my best suggestion is to create two separate xprofile fields, and name them accordingly: ‘Start Date’, ‘End Date’ or something like that.
That is exactly what I did, that was only way around I found for time being. If you have any insight can you pls tell me if it is possible to have a field with JQ datepicker where I can select start and end date. I’m planning to create a filed like this just need something to start with.. that’s the hard part once I’ll have a slate to start with I can write what I want. I’ve no issues getting my hands in code I’d rather enjoy it.
