Why I can't edit the time on a photo

Time and location are locked at capture by design. Here's what you can still edit, plus how to fix a wrong timezone.


Timemark locks the timestamp and GPS location on every photo at the moment of capture. These fields can’t be changed afterward, by design.

The timestamp and GPS coordinates are the core of Timemark’s photo verification. Locking them after capture keeps the Photo Code tied to the original capture record.

Editing the timestamp or location would invalidate the Photo Code and break verification in Verify Center.

You can still change these after a photo is taken:

  • Watermark fields: Notes, title, and other template fields, via Edit watermark.
  • Logo: add, crop, or replace the logo on the watermark.
  • Template layout: switch or adjust the template style.

Timemark gets the photo time from Timemark’s servers. It gets the time zone from your phone’s location. Daylight saving time is applied automatically.

Most time problems are fixed by refreshing the time and time zone:

  1. Turn on location for Timemark in your phone settings.
  2. Connect to the internet.
  3. Open Timemark again.

The time is off by several hours, or shows the wrong time zone (for example GMT-5)

After travel, the app may still use the time zone from the last place it synced.

  • Use the refresh steps above.

The time is off by exactly one hour

First, use the refresh steps above. If it is still off by one hour, your phone may not have the newest daylight saving time rules. This can happen on some Android phones.

The time shows --

Timemark shows -- when it cannot confirm the real time. This can happen if the app has not connected to the internet since it was installed or since the phone restarted.

  • Connect to the internet and open Timemark again.

Time and location are locked at capture. Fixing the time only changes photos you take afterward.

To avoid it: turn on location for Timemark in your phone settings and connect to the internet before taking photos in a new place.
