Daily activity and time use survey

Hi,
I am completely new to qualtrics. For my PhD, I have to conduct a daily activity and time-use survey. The respondents will have to reply/ fill up the same questionnaire for 7 days in a row. Do anyone have conducted such a survey before using qualtrics?
For me it is important to know which activity they are doing from a drop down/ drill down type question. Additionally the time stamp: start and end time.
Any advice/ideas from the community on how best to set up a survey like this? Any available code for the time stamp design (start and end time for an activity).
Thank you advanced.
Best,
Morshed
