One possibility: Your uptime is short, and your hwclock is set to local time. Wait some hours, check again, and you should see those that had no time have since acquired times. Cause is timestamp was created in the future due to disparity between RTC and hwclock early in boot.

Yes valid time has appeared after some time.
