In Liberia, we’ve been running into a problem around collecting time stamped data. Our users are 100% offline. CHAs often drain the entire battery on the phone, which resets the date, usually to 01/01/2017. This means that timestamps are inaccurate and makes it much more difficult to conduct data analysis.
Right now, the only way to fix this is to manually update the date/time on the users’ phone. With 4,000 users in remote areas, this is super unfeasible on a regular basis. Anyone have any brilliant ideas on how we could solve this?
