Summary
Time Manipulation is the ability to alter time. The exact mechanics and the effects of this ability may vary, but the most common examples are time travel, time stop, and speeding up/slowing down time. Certain users are able to control their abilities such that their Time Manipulation only affects certain targets, but it's not unusual for Time Manipulation to apply across all of what a verse considers "time" or subject to it.

Notes
1) It's very common for verses to treat space and time as inseparably linked, forming a spacetime continuum and combining Spatial Manipulation with Time Manipulation in some capacity. The exact implications of this link varies depending on the verse, and in some cases space and time may not be considered linked together at all.
2) Although time is commonly referred to as being the fourth dimension, it is important to note that this does not necessarily imply that it is a spatial dimension. More commonly, time is referred to as the "fourth" dimension in the sense that spacetime is comprised of three dimensions of space and one dimension of time, forming a 4-dimensional spacetime continuum. Because of this distinction, it is incorrect to assume that all entities with higher-dimensional existence are inherently immune to Time Manipulation, although it is not uncommon for certain verses to portray them as such and thus grant higher-dimensional entities a form of resistance to Time Manipulation.
