Time server off by 30 minutes?

[Shark92651]

I noticed this morning on my home BlueIris system that the time on my cameras was off by 30 minutes. I am using the camera OSD only so I went to look at the time settings. It was configured to use time.windows.com. Since I am having success running the W32Time service on my BlueIris servers at work, I setup my home to use the same. I enabled the time service on my BlueIris PC, entered the IP address for the NTP server, clicked Test, was successful, yet the time is still off by 30 minutes (behind). I changed the update interval to 1 minute and waited, but still never synced properly. If I click the box to sync with my PC, the time updates correctly. Does anyone know what may be the issue here?

I'm guessing your daylight savings time settings on the camera say to use a 30 minute offset (and the start/end dates are probably wrong too).

The key is that NTP time sync only shares what the UTC time is, and it is still up to the device to handle time zone offsets (which includes daylight savings considerations).

You are right. The cameras at my house have a setting called "DST Bias" and they were set to 30 mins. Swapping that to 60 mins fixed it. Thanks!
