The Virgo detector is a kilometer-scale interferometer for gravitational wavedetection located near Pisa (Italy). About 13 months of data were accumulatedduring four science runs (VSR1, VSR2, VSR3 and VSR4) between May 2007 andSeptember 2011, with increasing sensitivity.  In this paper, the method used to reconstruct, in the range 10 Hz-10 kHz, thegravitational wave strain time series $h(t)$ from the detector signals isdescribed. The standard consistency checks of the reconstruction are discussedand used to estimate the systematic uncertainties of the $h(t)$ signal as afunction of frequency. Finally, an independent setup, the photon calibrator, isdescribed and used to validate the reconstructed $h(t)$ signal and theassociated uncertainties.  The uncertainties of the $h(t)$ time series are estimated to be 8% inamplitude. The uncertainty of the phase of $h(t)$ is 50 mrad at 10 Hz with afrequency dependence following a delay of 8 $\mu$s at high frequency. A biaslower than $4\,\mathrm{\mu s}$ and depending on the sky direction of the GW isalso present.
