Keep input time unit when parsing TimeValues

This commit modifies TimeValue parsing to keep the input time unit. This
enables round-trip parsing from instances of String to instances of
TimeValue and vice-versa. With this, this commit removes support for the
unit "w" representing weeks, and also removes support for fractional
values of units (e.g., 0.5s).
