Making it so timestamp variable gives UTC date & time instead of device-local time

[superuser-does]

Hello, I am trying to replicate TiddlyWiki's DateFormat in HTTP Shortcuts.

yyyyMMddHHmmssSSS gives me what I need in SimpleDateFormat syntax.

However, I need to shift the time to UTC+0 which is what TiddlyWiki stores its created and modified fields in by default.

Is there a way to turn the timestamp into UTC time within HTTP Shortcuts please?

Currently, the Timestamp variable does not support this, but I will see that I can add support for this in the next version of the app.

Until then, you can try this workaround:

1. Instead of a Timestamp variable, create a Static Variable. Let's assume it is called "myTimestamp"
2. Edit your shortcut and go to "Scripting"
3. In the "Run before Execution" text field, insert the following code snippet:

const timestamp = (new Date()).toISOString().replaceAll(/[^0-9]/g, '');
setVariable("myTimestamp", timestamp);

This will generate a timestamp in ISO string format (e.g. "2026-06-06T14:31:15.762Z"), strip all non-digit characters from it, and then assign the resulting value into the "myTimestamp" global variable.

Thank you! A checkbox to always return UTC time would be fantastic.

Just want to say thanks for putting this in, looking forward to the next release - and a massive thanks of course for the impressive and intuitive app you created in the first place.
