Times 25346 - Struggled a bit

I went over the hour by a few minutes on this one. I didn’t have problems starting but I couldn’t get it to flow so I was constantly hopping around the grid putting in odd words here and there. I can't say I enjoyed it much but I think that's mainly down to the pressures of blogging as it's all perfectly fair and accurate as far as I can see. The only definite unknown word or meaning for me here was the hidden answer.
