My IP cameras (IPOB-EL1MPIR50-E) are not in sync with my NVR (32 channel). It appears that the NVR has the correct time. Does the NVR push the correct time out to the cameras? How do I get them back in sync?
Check the NTP servers on both devices and ensure that the Gateway as well as the DNS Addresses are correct to your network.

You will use IE to connect to the cameras IP address. If your recorder has a built in PoE Switch connect the computer to one of the PoE Ports and scan with the Config tool then use the IE to check the settings. Default username and password is admin/admin.
Here is an article on how to connect to the recorder or built in PoE Switch to see the cameras and configure them.

I thought NTP was working on all 3 NVRs but now I don't think so. The times are off by a few minutes from each other. wouldn't they be the same if NTP was working?
I also try and do a manual update on the NTP server, time.microsoft.com and I get a failed message. Tried changing the IP address to other known NTP servers but I got the same message. Do I need to do something to my router to allow the NTP messages through? I didn't think so since the NVR is initiating the NTP request.

time.windows.com is known for it's glitchiness. There are a LOT of PCs in the world using it, which can cause delays in the update. If it continues to fail updates, you could try a different NTP server. ( time.nist.gov is a good one) NTP works on UDP port 123, so make sure there are no blocks in Firewall = check Firewall logs to be sure.
As for cameras on built in POE on the NVR = these will not connect to NTP server - there is no direct path for them to access the Internet. I have always advised for IP cameras = turn off the time and date in the cameras OSD (On Screen Display) and just let the NVR time stamp them. (Time on cams on a built in POE will always 'wander' because they can't connect to NTP servers.) Better to just turn off that display than have a sharp attorney contest your video evidence because of time being incorrect.
That's my two cents.....
