[samad-yar-khan]

Description

• Currently the speaker speaker schema does not have a date_time field to specify the time and date of the speaker session / talk.
• The speaker schema does not have a duration field to specify the estimated duration of a speakers talk on the main stage.
• The live and ended fields of the speaker schema have to be manually updated to specify if a speakers session is currently live or if it has ended.

Expected Behavior

• Auto Updation of Live and Ended fields according to date_time and estimated time_duration of the talk
