"???" in timestamp column in MAX

[Wilm2]

I noticed today some checkmarks "???" in the timestamp column in my MAX 4.4.0.49152.

Why is this and how can I change it? Never saw it before.

The question marks usually mean it doesn't know when it last got an update.  Probably the last time it received an update on that channel was before MAX started running.

If you force a value change on the channel, it should update. 

Why do you want to change it?

It's just something I didn't see before. I want to make sure nothing is wrong.

Propably MAX started indeed after the last change of the measurement.

thx

I wouldn't worry about it.  I see it often enough.  How often you see it probably depends on the nature of your channels and frequently they update.  I think the timestamps should probably include the date as well.  When I went to MAX I saw some timestamps that were from later in the day than the current time.  So they had to be older than today.  Perhaps even several days old for all I know.

What you see is not unusual.
