Improve functionality of CString-to-Interval parser

[manh9203]

This pull request addressed problem #2882 by modifying the way time is imported within Intervals. The problem is because the time is exported in the format of hh:mm:ss, which the parser couldn't handle during import. The modifications include adapting Interval::fromCString to accommodate this format. Additionally, the updated parser now supports new date specifiers such as millennium, century, decade, quarter and week, along with partial numbers for time values.
