The publisher is not responsible for any errors or omissions in this version of the manuscript or any version derived from it. The Version of Record is available online at [10.1088/1538-3873/aaa7e7].We report a long-term (1961-2017) study of the eclipse times in the dwarf novae WZ Sagittae, in an effort to learn its rate of orbital-period change. Some wiggles with a timescale of 20-50 years are apparent, and a connection with the ~23 year interval between dwarf-nova eruptions is possible. These back-and-forth wiggles dominate the O-C diagram, and prevent a secure measurement of the steady rate of orbital-period change.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/AccretionAccretion disks(Stars:) binaries (including multiple): closeNovae, cataclysmic variablesStars: individual (WZ Sagittae)journal article10.1088/1538-3873/aaa7e7open access21 Astronomía y Astrofísica
