Include fractional seconds in all formats of event time
Created by Peter Shawhan on January 13, 2017. Copied from redmine (https://bugs.ligo.org/redmine/issues/5012)
When the Event Time (near the top of the page) is given as GPS, it includes fractional seconds. However, the other formats (LLO Local, LHO Local, UTC, Virgo Local) are all truncated to be an integer second. (Actually it's not clear at a glance whether GraceDB is rounding or truncating, but I think it is truncating.) It would be helpful to include the fractional part of the second in those formats too.
