Retrieving Date/Time/Number format from Windows

15 Jun 2016, 02:58

Hello there,
I'm wondering how I can retrieve the current windows settings for the date/number formatting.

What I need this for is to be able to input existing, given dates/numbers (from an excel sheet) into a tool that requires a specific date/number format.
If I use COM objects to retrieve the dates/numbers from Excel, they are retrieved according to system locale/format settings, so I need to know what they are so that my script can auto-convert them to the correct format.

Until now I've used a rather crude string split, etc. but it can easily cause severe errors as it's not capable of differentiating US dates (MM-DD) from EU dates (DD-MM), or dates where the year is in a 2 char format (e.g. DD-MM-YY vs YY-MM-DD).

Similarly, for numbers it causes issues if the decimal and/or thousands separators vary (e.g. 1,234.789 vs 1.234,789). In this case, if the numbers were always formatted exactly the same (e.g. 3 decimal places) then it might not be an issue, but as it's not the case (anything from 0 to 6 decimal places, with numbers anywhere between 100 000 000 and 0.000001) it's rather hard to have this fool-proof.

Anyhow, thanks in advance for any ideas on how to solve this.

There is a variable in AHK that you can retrieve the full Date string: A_Now
Then you can format as you want with FormatTime command.
Please see the documentation.

Hi Dust,
Thanks, but that's not really what I'm looking for. What I'm trying to do is the reverse, retrieve the EXISTING date/number format from Windows, and then use that to know what I need to do to convert a series of existing dates/numbers (already formatted - incorrectly) into the format I want/need.

For GetNumberFormat & GetNumberFormatEx I did the translation already => WinAPI - GetXxxFormat Functions

This might give you some values of interest:

I was hoping to silently let that go, but, yes, I deleted it myself - I thought it was the wrong approach when, as already mentioned, GetDateFormat etc. exists. I only looked at GetLocaleInfoEx, so what I posted wouldn't run on XP, and your code appears to handle more cases, so your post is better than what I had anyway.
