- The first seven timesteps were specified as steps of length 365/7.0 days,
when converted to seconds one second was lost due to rounding. This has been
changed by using integer length TSTEP.
- assertEqual() statements use full datetime; which has been shifted one full
day forward to account for rounding errors due to the lost seconds.
- EclipseState.getFirstRestartStep( ) is changed because we have configured to
get restart data for the first report step every year, and that is now step 7
instead of step 8.
