OneSpan Callback not returning GMT-0 time

0 votes

I am currently in CST/ GMT-5 but the callback is returning GMT-4 for the createdDate time.

I am on the onespan sandbox could this have an effect?

 

Edit: updated subject to GMT-0 time

Hi Nemo,

 

Thanks for your post! Please note that the Date String OSS callback service returns is always in GMT time, an example looks like below:

{"@class":"com.silanis.esl.packages.event.ESLProcessEvent","name":"PACKAGE_CREATE","sessionUser":"18EZDL44xgsX","packageId":"wVdZEaPD2igwUnFGJBjDD0dpO7k=","message":null,"documentId":null,"createdDate":"2018-06-30T20:04:55.384Z"}

It's in format of: yyyy-MM-dd'T'HH:mm:ss'Z'

 

In Java Code, if you are using ZonedDateTime to convert time zone, it could look like below:

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";
        ZonedDateTime zonedDateTime;
        if (zoneId.length() == 3) {
            zonedDateTime = gmt.withZoneSameInstant(ZoneId.of(zoneId, ZoneId.SHORT_IDS));
        } else {
            zonedDateTime = gmt.withZoneSameInstant(ZoneId.of(zoneId));
        }
        System.out.println(zonedDateTime.format(fmt));

 

From the screenshot you supplied, I think the 1 hour offset might be caused during this conversion 

 

 

On the opposite, if you are converting local time to GMT time, you can use code similar to below:

Local ---> GMT

        Date date = new Date();  
        String strDate = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'").format(date); 
        ZonedDateTime utc = ZonedDateTime.parse(strDate);

        ZonedDateTime zonedDateTime2;
        if (zoneId.length() == 3) {
            zonedDateTime2 = utc.withZoneSameLocal(ZoneId.of(zoneId, ZoneId.SHORT_IDS));
        } else {
            zonedDateTime2 = utc.withZoneSameLocal(ZoneId.of(zoneId));
        }

        ZonedDateTime utcZonedDateTime = zonedDateTime2.withZoneSameInstant(ZoneOffset.UTC);
        System.out.println(utcZonedDateTime.format(fmt));

 

For time zone ID, you can get a list of OSS supported time zones from this API:
GET /api/eslTimeZones

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?

        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.

Hi Nemo,

 

I can confirm that all time string OneSpan Sign sends to you are in GMT (GMT-0) time. A quick proof is that you can print out the callback payload in plain text and check the value. Below is an example that OSS callback service just sent to me:

{"@class":"com.silanis.esl.packages.event.ESLProcessEvent","name":"PACKAGE_CREATE","sessionUser":"ATQOPd60xE4V","packageId":"3wyKgrhFUiOXnl7oC_I_3-183Qk=","message":null,"documentId":null,"createdDate":"2022-09-20T17:22:26.270Z"}
