ADC_Keywords: Stars, variable ; Photometry Keywords: stars: individual (KZ Hya) - stars: variables: other - techniques: photometric Abstract: We present 109 new times of maximum light of the SX Phoenicis (SX Phe) star KZ Hydrae (KZ Hya) based mainly on our extensive photometric observations for two decades, leading to determination of a general ephemeris combined with the data in the literature. Description: In total, more than 135h of data were collected on 54 nights at five observatories with either photometers or CCD cameras for KZ Hya from 1988 to 2007.

Note (1): Note that for number 96 the Tmax follows Liu et al. (1991IBVS.3606....1L). It is incorrect in Table II of Doncel et al. (2004, Ap&SS, 290, 399). Also for numbers 131-134 and 136-143 the Tmax values are 0.5 day less than the values listed in Table II of Doncel et al. (2004, ibid.) Note (2): References as follows: 1 = Doncel et al.
