Set your store time zone for pre-order dates
The store time zone in Timesact sets the time zone your dates are read in: product Start and End dates, the pre-order shipping date, the date to charge the rest of a split payment, and countdown timer times. Every store starts on (GMT+00:00) UTC, so choose your own time zone first, then set your dates. You find it in Timesact under Billing & Account → Store settings → Time zone, on every plan.

Before you start
- New stores start on (GMT+00:00) UTC. Timesact keeps its own time zone setting, separate from the one in Shopify.
- To match your Shopify store, look up the zone in your Shopify admin under Settings → General → Store defaults → Time zone.
- Set the time zone before you schedule products, so every date you save reads in your local time from the start.
How to set the store time zone
- In Timesact, open Billing & Account.
- Open the Store settings tab.
- In the Time zone section, open the Time zone list and choose your zone, for example (GMT+01:00) Amsterdam, Berlin, Rome, Paris.
- Click Save in the save bar at the top of the page. Timesact confirms with Store settings saved.

Where the store time zone applies
The store time zone is used for these dates:
- Start date and End date on products and variants (in Products, and in the CSV upload's start_date and end_date columns).
- The Shipping date of a Customer Experience whose shipping is set to Exact date (Experiences → your Customer Experience → Admin → Functionality settings → Pre-order → Shipping).
- Date to charge the rest for a Split payment with When to charge the rest set to On a specific date.
- Start date & time and End date & time on a Countdown to a date timer.
Each of these date fields shows the zone in use in its help text, for example "Times are in Europe/Paris timezone".

How Start and End dates work with the store time zone
Product Start and End dates are whole days. Each one begins at 00:00 in your store time zone.
- Start date: the Customer Experience goes live on the variant at the start of that day.
- End date: the Customer Experience stops at the start of that day. To keep a pre-order open through 31 December, set the End date to 1 January.
- Timesact checks Start and End dates once an hour, so a date takes effect within about an hour of 00:00.
Countdown timer dates carry a time of day as well, so the timer counts to the exact hour and minute you set.
Changing the store time zone later
Dates you have already saved keep the same moment in time when you change the store time zone, and the app shows them in the new zone. A product Start date can then show as the day before, and a countdown time that started at 00:00 can show as 23:00 the day before. To have a saved date follow the new zone, open it, set the date you want again and save.
Questions merchants ask
Does Timesact use my Shopify time zone?
No, Timesact has its own setting under Billing & Account → Store settings → Time zone. Every store starts on (GMT+00:00) UTC, so choose the same zone as your Shopify store.
My pre-order ended a day early. Why?
The End date stops the Customer Experience at 00:00 on that day, in your store time zone. To sell through the whole of a day, set the End date to the following day.
I changed the time zone. Do my scheduled dates move?
No, saved dates keep the same moment in time and are shown in the new zone. Set them again if they should follow the new zone.
Which time zone does the date picker use?
The store time zone. The help text under the field names it, for example "Times are in America/New_York timezone".
Can I set a start time, not just a start date?
Product Start and End dates are whole days that begin at 00:00 store time. For a specific hour, use a Countdown to a date timer, which has Start date & time and End date & time.
