  There are two types of timing irregularities seen in pulsars: glitches and
timing noise. Both of these phenomena can help us probe the interior of such
exotic objects. This article presents a brief overview of the observational and
theoretical aspects of pulsar timing irregularities and the main results from
the investigations of these phenomena in India. The relevance of such Indian
programs for monitoring of young pulsars with the Square Kilometer Array (SKA)
is presented, highlighting possible contributions of the Indian neutron star
community to the upcoming SKA endeavour.
