What do you see when you use that format? It could be that the colon ":" character is causing problems, since this is an invalid character in windows filesystems. Omniscope should handle this case and either convert or show an error - we'll check this.

Try "d-MMM-yyyy H-mm-ss" instead. Or, if you want a format that appears in chronological order in Explorer, use "yyyy-MM-dd HH-mm-ss".

Thanks Steve.
d-MMM-yyyy H-mm-ss works

Steve, perhaps good idea to add a short comment line in the DM block that you need to make use of the '-' in stead of the ':' as mentioned on the visokio website.

It should do this already; we're investigating.

If you enter a date format that cannot be exported as a filename the following error should be shown:

The filename timestamp contains one or more invalid characters: " : \ / ? * > | Please adjust the format so that these characters are removed.

Do you see this error message?

Update: we have changed the default timestamp format to be "yyyy-MM-dd HH-mm-ss-SSS", i.e. filename-friendly dates & times with millisecond precision.

@steve - do you guys have guidelines for what the different combinations of datestamps can output? I've been playing with this today - based on what I thought I understood from Excel and been getting some strange dates output. For example using mm (apparent random number) gets me a very different output from MM (03).

Hi,

"mm" gives you minutes and "MM" gives you hours. This is why you get different results.

The following page provides a guidelines on how to use date formats:
