Viatom Data Importer - Options RegEx Purpose?

[DavidEsp]

When (in OSCAR) importing data via [Data > Import Viatom/Wellue Data],
(on a Mac), the file-selector-browser appears with a strange-looking dropdown-selector at the bottom of it. What is it for? Or what does it represent?

If I click the Options button, then this selector toggles on/off from being displayed. I guess its default state ought to be "Off".

The options presented by the dropdown-selector (and, in part initially displayed by the default selection, before clicking it) look like Regular Expression (RegEx) codes.

Example:
"*20[0-5][0-9][01][0-9][0-3][0-9][012][0-9]:[0-5][0-9]:[0-5][0-9]"

Suggestive of a timestamp as follows
e.g. "2023123123:19:12"

The other selection-option's code being the same thing but (more prettily) with dashes between the components of the date and a space separating the time
e.g. "2023-12-31 23:19:12"

So I guess I got that right - but still, what is it for? Is it something to do with interpreting the binary data? Or how it gets presented somewhere? Given it's binary, it (presumably) doesn't include prettifying things like dashes and colon characters, and I wouldn't expect it to have ASCII characters representing the digits either.

So I am a confused user (as well as an intrigued geek).

DavidEsp,
To satisfy your curiosity about the regex...

Over time the Viatom/Wellue developers have used different file naming conventions based on the model and also software version. So the two regex lines covers them all (to date).

The Viatom developers seem to change things with almost every software update, so those regex lines may change over time.
