As of 14.1, TimeValue required Cashflow arguments to consist of uniformly sampled data. This code is an example:

cf = Cashflow[
   {{{2024, 1, 16}, 324.67}, {{2024, 2, 6}, 634.09}, {{2024, 11, 20}, 
     356.27}, {{2023, 12, 31}, 0}}];

TimeValue[cf, .05, {2023, 1, 1}]

 (* TimeValue::unisp: Uniformly sampled data expected at position 1 in Cashflow[{{{2024,1,16},324.67},{{2024,2,6},634.09},{{2024,11,20},356.27},{{2023,12,31},0}}]. *)

I am running Mathematica desktop 14.1 on Win 10 Pro.

This issue did not occur in previous versions.

On 19 August 2024, I reported this to tech support and received this reply: "It does appear that TimeValue has regressed in 14.1. I have forwarded an issue report to our developers with the information you provided, and added your contact information to the report so that you can be notified when it is resolved."

I believe some of you have access to a beta release of version 14.2. Would someone please check to see if this issue has been fixed. If not, I perhaps have a chance to advocate for a fix before the final release of 14.2.

Thank you.
