Attached is the picture showing the event callback time.

Yes please raise a request. Since the Callback size documented is 255 characters as displayed here https://community.onespan.com/documentation/onespan-sign/guides/feature-guides/developer/setting-callback-notifications, there seems to be missing information on how the packageId is generated and if it will ever be longer that 28 digits.

Shouldn't OneSpan callbacks be sending the timestamp using GMT-0 as mentioned here? https://www.onespan.com/blog/onespan-sign-release-1121-time-zone-support

I am aware that there is a difference between my local time and the callback time, but I was expecting the callback to send the timestamp using GMT-0 and not GMT-4
as displayed in the blog. Since I am tracking the status on our application using these timestamps, I need to know which time zone I should use.

Can you confirm that the onespan callbacks are using GMT-0 or GMT-4?

GMT ---> Local

        ZonedDateTime gmt = ZonedDateTime.parse("2022-09-19T14:13:00Z");
        DateTimeFormatter fmt = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss'Z'");

        String zoneId = "America/Montreal";

Also from this code you shared, America/Montreal is GMT-4 which seems like that is what timestamp the callback is using.
