Bookings displaying or saving at the wrong time relative to what a customer actually selected usually comes down to a mismatch between the site’s configured timezone, the booking plugin’s own settings, and the visitor’s browser — three separate places timezone information can disagree.
Book a test slot and compare what’s confirmed against what you selected
Make a test booking for a specific, known time and check what actually gets confirmed and recorded. A consistent offset (always a fixed number of hours off) points at a configuration mismatch rather than a random, unpredictable bug.
Timezone handling errors in bookings
Booking times off by a consistent offset, traced to a timezone mismatch between WordPress, plugin, and browser.
- Full backup taken before we start
- If we can’t fix it, you get your money back
- We never ask for your own password
This or something else?
| Bookings are recording or displaying at the wrong time | This fix covers it |
| The issue is general availability accuracy, not specifically timezone | Booking calendar availability errors |
| You want locale and date format corrected more broadly, not just booking times | Locale & date format configuration, in the Content & Updates bucket’s Multilingual category |
| Bookings are correct but reminder timing is off | Appointment notification failures |
What you are seeing
- A consistent time offset between what was selected and what’s confirmed
- Availability windows appearing shifted from their intended hours
- The issue possibly only affecting customers in specific timezones
- Correct times in the admin view but wrong times shown to customers, or vice versa
Common causes
- WordPress’s core timezone setting not matching the business’s actual location
- The booking plugin using its own, separately configured timezone setting
- The plugin not correctly accounting for the visitor’s own local timezone when displaying times
- A daylight saving transition not handled correctly by one of the systems involved
- The server’s own system clock running on a different time than any of the site’s configured settings
What we do
- Reproduce the specific time discrepancy with a test booking
- Check WordPress’s core timezone setting against the booking plugin’s own setting
- Correct any mismatch between the two
- Verify visitor-facing times display correctly relative to their own timezone where applicable
- Test across a daylight saving transition if one is relevant
- Confirm admin and customer views now agree
What is included
- The timezone mismatch identified and corrected
- Verified accurate times across admin and customer views
- Testing across a daylight saving transition where relevant
- The pre-fix backup, kept for 30 days
Not included
- General availability accuracy issues unrelated to timezone specifically
- Broader locale and date format configuration beyond booking times
- Notification timing issues, a separate, related fix
- Ongoing monitoring for future timezone-related issues
Questions about this fix
Why would WordPress and the booking plugin have different timezone settings?
Some booking plugins maintain their own timezone configuration independently of WordPress's core setting, and if the two were never explicitly aligned when the plugin was installed, they can quietly disagree from day one.
Could this affect customers differently depending on where they are?
Yes, if the plugin doesn't correctly account for a visitor's own local timezone, someone booking from a different region than your business could see times that don't match their own local clock.
Is daylight saving time a common cause of this?
It's a real, recurring risk — a fix that works correctly most of the year can still misbehave specifically around a daylight saving transition if the underlying handling isn't genuinely robust.
Do existing bookings get corrected too, or just new ones?
This corrects the configuration going forward — existing bookings retain whatever time was originally recorded, since we can't be certain what time a customer actually intended without asking them directly.
How would I notice this myself before a customer complains?
Making a test booking for a specific, known time and checking what's actually confirmed is the most direct way to catch this yourself.

If this is the second time this year
A bad update breaking the site is a symptom of updates not being tested first. Care plans run every update on a staging clone before it reaches your live site, which is the actual fix for this happening again.
Your access, your rules
Create a separate admin account for us and delete it when we are done. For anything else, we get in touch and agree a method — never a form field on this site, never by reply to an email.
We back up first, always
Before anything is touched we take a full backup and keep it for 30 days. If a fix goes wrong, we put the site back exactly as it was.
If it is not what you bought
If the problem turns out smaller than what you ordered, we refund the difference. If it is bigger, we stop and send a quote before doing any extra work.
If we cannot fix it
You get back what we received. Diagnosis is on us — you only pay when the problem is actually solved. The payment processor takes its fee before the money reaches us, so we never hold it and it is not ours to return. That is true here as everywhere else.
If it comes back
Reply within seven days of delivery and we put it back on the bench at no cost. The fix is not finished until it holds.
What we are responsible for
If something goes wrong with a fix, our responsibility is limited to what you paid for it. We take a full backup first so mistakes can be undone, and we tell you before doing anything outside what you bought.
