I sometimes get these errors about timestamps, in my chat+cashu app, where CDK generates this error: Mint time outside of tolerance. This was with coinos.io, but I think I've seen it with others too. With coinos, sometimes it works and sometimes it doesn't.

Update: Here's a straightforward example. I put in some logs. I'll try to find a way to contact the mint, and close this

The mint is sometimes about 20 minutes behind. I verified my wallet's time with https://time.is/Unix_time

Mint time does match wallet time. Mint: 1760686887, Wallet: 1760687877
TRACE /home/satsandsports/MyCode/Cashu/mdk_ecash/cdk/crates/cashu/src/nuts/nut01/secret_key.rs:165 Secret Key dropped.
Error: Failed to receive token: Failed to receive token: Mint time outside of tolerance
AbortError: The user aborted a request.

I removed the timecheck from the cdk and am continuing to test, so far this seems to be working:

Although, of course we do need the correct time for various spending conditions, so I'm not proposing to remove this check

Interesting thanks for finding this. I've asked the nutshell devs if nutshell somehow caches the time or if the mints system clock is just off.

Either way the tolerance is not actually something in spec and something I just put in cdk, so I think we should maybe make this a softer error as it blocking a simple receive is not a good experience. However, as you point out is an import check for spending conditions, so it should probably be in the spec more specifically as if someone is doing conditions with short term timeouts even 20 min could make a difference.

I deleted my comment from 20 minutes ago, because I discovered my clock was a bit off! Sorry about this

Now I'm not sure if I trust any of the data I've presented here :-)

No worries brings up a good point even if the data is a little off.

Cdk does store it but it only check the the time when it fetches it from the mint.
