http://kenno.wordpress.com/2006/08/03/vim-tip-insert-time-stamp/
Tried it out, it works on my mac:
:r! date
produces:
Thu Sep 11 10:47:30 CEST 2008
This:
:r! date "+%Y-%m-%d %H:%M:%S"
produces:
2008-09-11 10:50:56 |
For a unix timestamp:
<pre>
:r! date +\%s
</pre>
You can also map this command to a key (for example F12) in VIM if you use it a lot:
Put this in your .vimrc:
<pre><code>
map <F12> :r! date +\%s<cr>
</code></pre> |
:r! date
You can then add format to the date command (man date) if you want the exact same format and add this as a vim alias as well |
:r! date
You can then add format to the date command (man date) if you want the exact same format and add this as a vim alias as well

Maybe you could try it with operator overloading ? (Maybe a = operator which is not a method of your class) ?
Rect operator= (const Rect&,const rectangle&)
More about this in the C++ programming language by Bjarne Stroustrup or maybe on this page: [http://www.cs.caltech.edu/courses/cs11/material/cpp/donnie/cpp-... |
Create an intermediate shim type "RectangleEx", and define custom conversions to/from the 3rd-party string types. Whenever you speak to either API, do so through the shim class.
Another way would be to derive a class from either rect or Rectangle, and insert conversions/constructors there. |

The mechansism described under [6.2.5 Particular Templates][1] (under the section called bug/create/create.html.tmpl and bug/create/comment.txt.tmpl) works pretty well for us. Even though you say you don't want to create custom fields, adding some arbitrary HTML is easy enough.
