Dollhouse did time jumps a few times, actually mostly i think to retcon the shows dating (I'm convinced the first few episodes were meant to take place in Summer/Fall, 2008), but the real jumps, "Epitaph One" and "Epitaph Two: Return" notwithstanding, would be a few months between "Omega" and "Vows", the season one finale and season two premier with the time period used to explain away Echo's long term engagement (and I do mean engagement), another one happened about midway through the second season, the episode was..."Meet Jane Doe" I believe it was, wherein three months pass during the episode (one scene to the next, actually) which probably works for story purposes anyway (as not much apparently happens in those three months).
I think there were a few others here and there, but mostly in between episode time passing which obviously isn't to uncommon, a few seemed to somewhat be inconstancy, either from the actual (as opposed to intended or originally planned) airdate to catchup dates (Like I said, I am convinced for some odd reason I just cannot explain that season one is meant to be in circa Summer, 2008 the start at least, to being April, 2009 in the finale. The odd thing? Dialogue hints it's only been a few months). Season two, as I said, has that jump, and has references that counting the Jump, since "Vows" to..."A Love Supreme" has been about six months. when "Vows" was, I have no idea (arguments are of three to five months after "Omega")
Terminator: The Sarah Connor Chronicles seems to have done it as well, Season one takes place about September-November 2007 (Interestingly enough, that never clicked with me until I all out read about it), with season two for some reason, indicating (onscreen references) that it's gone from November, 2007-mid-2009 which is odd pacing if you ask me, the first three episodes take place within hours or days of each other.
It's my understanding that Heroes does it as well, but I am not sure if it's mostly between seasonal jumps, or if there's jumps during the seasons.
A recent episode of Stargate: Universe has had a time jump of about a month, albeit the episode actually took place during this month, but it is a month (or a month's worth of time at least) later at the end of the episode then it was at the beginning of the episode.
These probably are nothing significant per se, but it is time jumps, as the topic mentions...
