#ICE# I mean in detail.

1, GitHub is closed every Saturday and Sunday, and the domestic team will not have weekends. The start time for each update is around 3 or 4 PM, and the end time is at 8 AM, which is basically consistent with UTC time.
2. The team members displayed on the official website are all foreigners. I registered on the link and found the resumes of several team members, with real people showing their faces, no problem.
3. The time used is UTC (Coordinated Universal Time), and the active hours of the team on Twitter are consistent with the update time on GitHub, both are in UTC.
4, Zeus is indeed the team leader, online+ is the predecessor of online, it was a project of Zeus many years ago, there are materials, I remember there was an article published in either 2018 or 2019, which shows the date, and I have also posted it in a foreign group.
