Table property 'Empty if zero' doesn't work in EST US & Canada Timezone,

To elaborate more on this if we run the WinCC OA project in Indian Standard Time(IST) & Central European time(CET) , with above settings in place for table then time column with empty values displays nothing after table gets render on UI , which is correct behaviour.

If we run same project in Eastern Time (EST US & Canada) then time column displays a default date i.e. 1-Jan-1970 for empty value assigned, which is inconsistent behaviour.

Is there possibly a settings which we've forgotten to set when running in different Timezone or do we face a bug?

Thanks in advance,
Best regards,

I have tested it in 3.17 with a simple test panel and I cannot see the problem.
Which datatype have you chosen for the column where trhe option "Empty if zero" is set?

Hello Leopold,

Where using the following formatting:
Datatype of the content were writing to a cell 'time' via a dyn_dyn_anytype construction to directly apply color to the content.

The column in the table is formatted as:
Datatype: Time
Format: Custom -> %d-%b-%Y %H:%M:%S
H.Allign: Left
V.Allign: Object Default
Options: Empty If Zero

if the time-setting has a positive offset on UTC thus UTC+1 and further. All seems to work fine

If we apply a timezone UTC-1 and further the Option: Empty If Zero doesn't work anymore.

Could it be that a Negative offset on UTC give internally a 1969 year?

With simply changing Timezone and restarting of UI the effect is reproducible in our environment.

Maybe needles to say, but our test-environment is 3.16, we cannot test this yet on a 3.17 environment.
