Is one tenth of c close? At that speed time dilation is easy to observe.

Time dilation is observed at the speed of an aeroplane.

Oscillators currently studied in laboratories will in near future permit

Amost there:
0.3 meter of altitude is equivalent to about 9 km/h in speed.
More than walking, but already less than running,
