IO: ensure compatibility with 01-24 date formats

[dacoex]

In many engineering and measurement applications, the time is counted from 01-24 to indicate the end of a measurement or integration period.

This issue is to propose that pandas IO functions support importing such timestamps from CSV, Excel etc. out of the box and furthermore, Series can have a flag indicating the reference interval for integration or aggregation fo values (e.g. averaging).

there's been no interest in this in nearly a decade, and to be honest I don't really understand the request. clear input and expected output would help

closing for now then, if there's a need for this someone can open a new issue
