Excuse my ignorance regarding this question but I'm totally new regarding the matter of writing my own configurations, what I'm trying to achieve here is to create an SVG tag to the TimeStamp in `org-mode`.
Here is what I have achieved so far by hacking my way around:
("\\([0-9]\\):[0-9]".
((lambda (tag) (svg-tag-make tag :beg 1
:inverse t
:margin 0
:crop-right t))))
("[0-9]\\(:[0-9]\\)".
((lambda (tag) (svg-tag-make tag :beg 1
:end -1
:margin 0
:crop-left t))))
