Anything else?

Attu can't parse monotonic clock(m+=) in output of Time.string().
"created_time": "2024-05-11 20:05:21.922713137 +0800 CST m=+6.750931297", "updated_time": "2024-05-11 20:05:21.922713375 +0800 CST m=+6.750931533",
Another build from release works fine
"created_time": "2024-05-11 12:14:32.023107697 +0000 UTC", "updated_time": "2024-05-11 12:14:32.023109206 +0000 UTC",
Maybe it's the go version, idk, but add .Round(0) to

milvus/internal/querycoordv2/handlers.go

Lines 258 to 259 in 8a9a421

	CreatedTime: paramtable.GetCreateTime().String(),
	UpdatedTime: paramtable.GetUpdateTime().String(),

can eliminate this problem.
