Args
value	A value with a pre-specified time unit. Currently only supports 0 and datetime.timedelta instances.
picos	A number of picoseconds to add to the time delta.
nanos	A number of nanoseconds to add to the time delta.
micros	A number of microseconds to add to the time delta.
millis	A number of milliseconds to add to the time delta.

Raises
TypeError	If the given value is not of a cirq.DURATION_LIKE type.
