The second-generation laser interferometric GW observatories like advanced LIGO (aLIGO) plan to search for gravitational waves from compact binaries containing neutron stars and/or stellar mass black holes in inspiraling eccentric orbits. These weak and rare GW signals would be extracted from the noisy interferometric data by the method of `matched filtering'. This method requires theoretical templates that model such GW signals in an accurate and efficient manner. The implementation of templates involves providing accurate and efficient prescriptions to compute the temporally evolving GW polarizations states. We report on the development of numerical codes that provide ready-to-use post-Newtonian accurate time-domain inspiral templates for compact binaries in inspiraling eccentric orbits, and their implementation into the LIGO Algorithm Library (LAL). The ongoing efforts to compare the small-eccentricity limit of our templates with the existing LAL templates for quasi-circular inspiral will also be reported. Our effort to implement search templates for coalescing compact binaries in eccentric orbits via the EOB (Effective One Body) approach will be briefly presented.
