Super Productivity won't sync properly with Dropbox when the date has changed on one device

[Tim676o]

Steps to Reproduce

1. Change the date to a future one on an iOS phone.
2. Create some simple counters on the website, on the phone.
3. Reset to the original date
4. When synced with dropbox, you can see on Windows Super Productivity app and iOS web app an error : "Sync Error: one of the dates provided is from the future..." and then a prompt asking if you want to import the distant data or not.
5. If you accet to import the data, it takes you back to a setup of super productivity before the change of date on the iOS phone, wether on Windows or iOS, and it continues forever to display the same message if you try to sync, even if you imported the data. It doesn't change anything to restart the app.

Thank you very much for opening up this issue! I am currently a bit overwhelmed by the many requests that arrive each week, so please forgive me, if I fail to respond personally. I am still very likely to at least skim read your request and I'll probably try to fix all (real) bugs if possible and I will likely review every single PR being made (please, give me a heads up if you intent to do so) and I will try to work on popular requests (please upvote via thumbs up on the original issue) whenever possible, but trying to respond to every single issue over the last years has been kind of draining and I need to adjust my approach for this project to remain fun for me and to make any progress with actually coding new stuff. Thanks for your understanding!

I'm not sure if I fully understand the issue here. In what scenario would a date change on a device?

Not really sure if there is a good way around this. Since there are no servers with Super Productivity, we have to rely on the system time for these things.

I don't remember why I changed the date, maybe to check if something was available on some website if I brought forward the date. But now the bug seems to occur even when I did nothing. It occurs apparently from times to times. Simply relaunching the app solves it. I was afraid to do it because of potential data losses, but it wasn't harmful and sync is now working again.
