Generally, the more specific and concrete the question, the better.

Regarding your question, your description is not quite accurate. There seems to be a date-time stamp in addition to the key-value pairs.

The possible quotes around the values make it a little tricky. The simplest way to deal with those is to use the Text::xSV module with the set_sep set to a single space. The first three elements will be your date components and the rest will be the key-value pairs that you can split on the '='.

Another way to approach is to roll your own parser with a gammar derived from the structure of your line and some choice regexps. But I'd try the module first.
