It may be just me, and if it is, my apologies, but can someone please shed some light onto how shifts in CSI:NY works? They seem to work both night and day and at all hours, unlike the other two shows where there's a set shift time (I'm assuming). Do their shifts change on a daily basis or is there a set range? I'm guessing it's the swing shift - I just don't know what that is. Any info would be great, thanks.
