The bulk of STID, judging from the 2259.55 stardate, took place from late February to early March 2259. The closing scene, according to Kirk's speech, took place a year later, in early 2260. That was when the ship was recommissioned; perhaps there were several more months between the recommissioning and the start of the 5YM proper?
Of course, the comics' timing is already messed up because the "one year ago" line was added in post-production and the "After Darkness" comic wasn't aware of it. Now they seem to have overcorrected in the other direction.
