All of them fail. Looks strange. Would you please take a look? @wangrunji0408 Thanks!

Weird. They all passed on my local environment. 🤯
Seems like a Linux-only bug.

Yeah, you can start an EC2 in Singapore from risingwave AMI and see what's happening.

The memory layout of std::time::{SystemTime, Instant} was changed on Linux. 🥵
This issue will be fixed by madsim-rs/madsim#88
