By default, the Random Sampling process, that includes Guaranteed Sample Searches (GSS) if configured, runs at 1 AM local time, processes only items from yesterday and excludes today's items. Any item that was sent after midnight should be processed the next day. However, the midnight calculations are based on Greenwich Mean Time (GMT, also known as Universal Time Coordinate (UTC), time zone rather than the local time zone. If the local time zone is not the same as UTC, the local time zone's UTC offset from UTC will also be taken into consideration, i.e., added or subtracted from the item's UTC time. For example, if the Compliance Accelerator (CA) server is in Singapore, which is GMT +8, midnight will be calculated as 8 AM Singapore local time. Therefore, it will appear as only items prior to 8 AM were processed, and any item sent after 8 AM Singapore local time will be processed by the following Random Sampling run, including any GSS if configured

This is by design. If there is a need to process every item by midnight based on the local time zone, CA Random Sampling/GSS allows for this by processing everything up to the local midnight time and ignoring the UTC time conversion. This change can be made by connecting to the CA client using an account with sufficient permissions to make configuration changes, such as the Vault Service Account (VSA), and editing a Configuration setting, as follows:

1. Click on Configuration, then Settings.

2. Click on Configuration Settings at the top left corner while holding down the Ctrl key to show the Hidden Settings.

3. Expand Random Capture.

4. Uncheck the Exclude today's items from sampling (and process them tomorrow) setting.

5. Change the Sampling time (server local time) to 00 h:01 min  (This is equivalent to 12:01 AM local time or 1 minute past midnight).

6. Click on Save to save the changes and restart the Enterprise Vault Accelerator Manager Service (EVAMS).

NOTE: Making this change may cause Random Sampling not to run the next day at 12:01 AM as expected. This is due to the behaviour of Random Sampling running only once every 24 hours. Random Sampling should run as expected the following day, i.e. within 24 to 48 hours of making the change and restarting the EVAMS.
