Daylight Saving Time (DST) ends this weekend (Sunday, 6 April 2025) in Australia for most states. This means you’ll need to check your ASIC OTC derivative reporting is using the correct time settings after the time change.
Here are 2 tips to help you ensure your trades/transactions are reported at the correct time:
1. Check the Time fields in your handback files
It’s important to do the following check when you receive handback files for trades carried out after DST ends. Act promptly if there is any problem.
Cross check the time of your trades against the UTC time recorded under the following DTCC fields:
- ExecutionTimestamp field in your handback file. This field must match your trade Open Time.
How to check?
- Pick a few trades from your raw data and convert the time to UTC time; and
- compare those against the UTC populated under the above fields in your handback file.
In cases where you are not using Sydney local time as your server time, this check also aims to ensure you are reporting correctly where there are any changes in other time zones such as New York and London. If the time does not match, please contact us.
2. Check time recorded for daily snapshot (if applicable)
For firms who do a daily snapshot for ASIC trade reporting, double check if it is taking place at the intended end-of-day time.
With these simple checks above, you will save the time and effort from submitting corrections for your trades. This will also minimise breaches in the future.
If you have any concerns or are not sure how to do this check, please contact us.
