Frame Time (0018,1063) is the nominal time (in milliseconds) between individual frames of a Multi-frame image. If the Frame Increment Pointer points to this Attribute, Frame Time shall be used in the following manner to calculate 'the relative time' for each frame:
Frame 'Relative Time' (n) = Frame Delay + Frame Time * (n-1)
where: n = number of frame within the Multi-frame image and the first frame number is one
Note: When there is only one frame present, Frame Time (0018,1063) may have either a value of 0, or a nominal value that would apply if there were multiple frames.
