Does LogViewPlus support TAI64N date formats?

Yes, LogViewPlus supports the TAI64N date format as well as other variants of TAI dates. You will need to force identification of the date by specifying the format with: %d{TAI}

For example, if your log line looks like:

4000000056d4a439 my message

You can parse this by using a Pattern Parser with the format:

%d{TAI} %m%n

Variants of TAI are determined automatically.  All TAI dates are parsed with the same %d{TAI} override.

Hope that helps,
