Subject: [PATCH] Fix `Timestamp.IsZero` (#21593)

Our implementation of `IsZero` can't work. An "empty" timestamp (= 0)
calls `time.Unix(int64(ts), 0).IsZero()` which is always `false`. Only
`time.Time{}.IsZero()` is `true`.
We call this method ~~only at one place~~ and there the value
(`UpdatedUnix`) should be always != 0 so this PR may not have
consequences.
