I have uneven vertical space between two parboxes and between a parbox and beginning of a new text paragraph. How to fix these? Here is a minimum working example.
\documentclass{article}
\usepackage{calc}
\begin{document}
Hello 0!!
\parbox[t]{\textwidth-2.5cm}{\noindent{\textsc{\bfseries{First Document Management System}:} This is a long description of Document Management System. Very long indeed to fill two lines.}}\parbox[t]{2.5cm}{\hfill{2005-2009}}
\parbox[t]{\textwidth-2.5cm}{\noindent{\textsc{\bfseries{Second Document Management System}:} This is a long description of Document Management System. Very long indeed to fill two lines.}}\parbox[t]{2.5cm}{\hfill{2009-Present}}
\parbox[t]{\textwidth-2.5cm}{\noindent{\textsc{\bfseries{Last Document Management System}:} This is a long description of Document Management System. Very long indeed to fill two lines.}}\parbox[t]{2.5cm}{\hfill{2009-Present}}
Hello 1!!
Hello 2!!
\end{document}
I want a similar gap such as the gap between Hello 1 and Hello 2. between two paraboxes and similar gap between last parbox and Hello 1.
