Playback timeline differs from live view time

[allypally]

I have 5 Hikvision cams running through a Hikvision NVR. Since DST came into effect last week, when in LIVE view all cameras are displaying the correct local time. However, when I enter the PLAYBACK screen, the cameras still display correct time but the playback timeline is out by 1 hour. For example, if I am looking at playback footage for 16:00hrs, I have to go to the timeline at 15:00hrs.
My cameras are configured to NTP (au.pool.ntp.org) and the NVR is the same.
Can anyone explain why the playback timeline is different?

My cameras are configured to NTP (au.pool.ntp.org) and the NVR is the same.

OK, that's the time, but what is the DST setting on the NVR and cameras?
Is it enabled on both?

As I stated the settings are the same for the cameras and the NVR. That is they are all set to use NTP (au.pool.ntp.org). If I select DST for the NVR, it corrects the timeline for NVR Playback, but then changes all camera displays to 1 hour ahead. So, at say 8:00am local DST time, by using NTP setting, the cameras all display the current time, but in playback, if I wish to search footage from 8:00am, it shows on the timeline at 7:00am.
