A reminder that says “10:00” without a zone is a guess.
The patient may be looking at a phone that last synced in another city. They may have left DST on or off. They may have two clocks — laptop in one zone, handset in another — and they will pick the wrong one when they are already late.
The room does not move. The chair is in one building. The time on the email has to be that building’s time, written so a traveler can still translate it.
This is not another page about why 24 hours, 2 hours, and 30 minutes. That is the clock interval. This is the clock place. It is not opened versus confirmed. An open in Tokyo does not change 10:00 in the clinic.
Orvexify is a booking page plus email reminders. Confirm and Cancel sit in the mail. No patient app. No SMS. WhatsApp on Growth and Pro is coming soon. We do not publish a 70% figure.
“10:00” is not a time until you name the zone
Staff write 10:00 because they live in the clinic’s city. They never see the ambiguity.
Patients do.
- They booked from a work laptop in another state.
- They are visiting family.
- Their phone is still on holiday time.
- A calendar app converted the event when they tapped “add to calendar” — or it did not, and they think it did.
- DST shifted last weekend. The paper card in their wallet did not.
If the reminder only says 10:00, you have asked them to remember which of those clocks is the room. Many will guess. Guessing is how a confirmed visit still produces an empty chair — not because they did not care, because they arrived for a different 10:00.
Write the zone. Every time. Subject can stay short. The body must not.
The phone is a terrible source of truth
Do not “detect the patient’s timezone” and rewrite the visit.
That sounds kind. It is how you double-book the clinician.
The slot was taken in clinic local time. The next patient is also in clinic local time. If you shift the displayed hour to match a phone in another country, you have not helped them travel. You have told them a time the room will not honour.
The honest product:
- Slots on the booking page are clinic-local.
- Staff-added visits are clinic-local.
- Reminder emails print that same local time and the timezone name (or a clear abbreviation plus the city).
- The patient does the conversion, or their own calendar does, from a string that is not ambiguous.
If you want to be extra kind, put one extra line: “This is the clinic’s local time.” Do not silently convert.
Orvexify stores a real timezone on the clinic — the IANA kind (America/Denver, Asia/Karachi, Europe/London), not a frozen offset like “UTC−7” that breaks when DST starts. The mail should follow that setting. If the setting is wrong, every reminder is wrong. Fix the setting once. Do not patch it per patient.
What the email has to show
A reminder that works, for time:
- Clinic name they know
- Date
- Time
- Timezone (name or city, not only a number)
- Who they are seeing, if you have more than one clinician
- Confirm and Cancel when the visit is still pending — that sequence is a different page
Do not hide the zone under a logo. Do not assume “everyone here is MST.” Travel exists. Remote follow-ups exist. People forward the mail to a spouse in another city.
AM/PM still matters. A 24-hour clock is fine if your patients already use it. Mixing “10:00” with no AM/PM and no zone is how 10 at night becomes 10 in the morning in someone’s head.
The 30-minute note needs the zone too. Especially the 30-minute note. That is the mail they read in a car. If it only says “see you at 10,” and their phone says 9:12 in another zone, they will not do the arithmetic.
One clinic, one zone — on purpose
Orvexify is not a hospital network with six sites and six walls of clocks.
A two-doctor practice has one timezone on the account. Booking slots, dashboard, and reminders all read that zone. If you later open a second city, that is a different product problem. Do not pretend a reminder layer is a multi-location operating system. We are not chasing that.
If a locum flies in, they work the clinic’s clock, not the airport they left. Put it on the mail so the locum’s patients are not guessing either.
Staff should not run a private Google Calendar in a different zone than the booking page. The page and the reminder will disagree. Patients will believe the last mail they saw. Make that mail match the room.
Booking page and phone bookings use the same zone
The public link is optional. The zone is not.
If they pick 10:00 on the booking page, that 10:00 is clinic-local. The confirmation mail must not “helpfully” show 12:00 because their browser said New York.
If they called and staff typed the visit in, it is the same 10:00. Same mails. Same zone on the page. A reminder that only exists for “online bookings” is a second, worse process — and a reminder with a different clock than the paper card is how you get two arrivals for one chair, or none.
Confirm from email, no app is the tap. This page is only whether the time next to that tap is honest.
DST is a clinic setting, not a patient hobby
Twice a year, a frozen offset is wrong.
If your software stores “UTC−5” in July and still says UTC−5 in January, every reminder after the change is off by an hour. Patients who live in the same city as the clinic will still be late or early. Travelers will be worse.
Use a timezone name. Let the library apply DST. When the region does not observe DST, the name still works. When it does, you do not send a week of wrong 24-hour mails because nobody edited a number.
After a DST change, glance at Monday’s list. If the first three reminder times look shifted against the wall clock, the setting was an offset. Fix it before Tuesday.
Do not send a special “DST is coming” marketing mail. That is a newsletter. A visit reminder is not a newsletter.
What this is not
- Not detecting the patient’s phone and rewriting the slot.
- Not six locations on one account.
- Not Google Calendar sync (that is coming soon, not live).
- Not SMS. Not a 70% badge. Not fake clinic counts.
- Not live reschedule from the email. Confirm and Cancel are the taps.
- Not WhatsApp as live. Email is on every paid plan; WhatsApp reminders are coming soon on Growth and Pro.
- Not an EMR.
How Orvexify uses the zone
On how it works:
- The clinic picks a timezone from the full world list.
- Booking slots are in that zone.
- Reminder emails at 24 hours, 2 hours, and 30 minutes are scheduled from that clock, not from whoever opened the dashboard on a laptop in another country.
- The mail should print the clinic-local time so the patient is not guessing.
If a staff member logs in from a trip, they are still looking at clinic time. The room did not follow them.
Starter is $14.99/month (two doctors, 300 appointments in a calendar month). Growth is $29.99. Pro is $69. All three are for sale. Yearly is ten times monthly. No card to create an account.
Empty hours still cost. Use your own fee in the no-show cost calculator.
A week of catching the wrong clock
- Open one reminder you actually sent last week. Find the zone. If it is missing, patients are guessing.
- Check the clinic timezone setting against the wall clock in the reception. If they disagree, every future mail is wrong.
- Ask one traveler — someone who booked from another city — what time they thought it was. If they say “I converted it myself,” your mail was incomplete.
- After the next DST change, read Monday 8am against the first reminder timestamp. One hour off means you stored an offset.
- Do not add a second “patient timezone” field and then argue with the diary. One room, one zone.
A Thursday that only works if the zone is written
Twenty visits. Not a hospital.
Two patients booked while visiting. One phone is still on the city they flew from. One laptop calendar auto-converted; the other did not.
If the reminder says “Thursday 10:00” with no zone, you have two different 10:00s in two heads and one chair.
If the reminder says “Thursday 10:00 AM Mountain Time (clinic local),” both travelers can be wrong in private and still arrive for the room. The local patients ignore the extra words. That is the point of extra words.
None of this needs a 70% slide. It needs 10:00 to mean the same hour on the board, in the mail, and in the doorway.
