The time stamp displayed on your Orchid POS invoices is determined by your timezone settings.
An incorrect time stamp can occur after daylight saving time starts or ends as Orchid POS does not adjust for that automatically (as not all locations take part).
The time that displays on the POS home page mirrors your current computer time.
If the time on invoices and receipts is incorrect, you need to adjust your timezone in Office > Back Office Settings > Store Settings (click Edit next to the store).
