Update CronScheduleTest.cpp

[nkinar]

Added test for update to Readme: event occurring every minute.

[PerMalmberg]

The test fails, you're missing the initial timestamp.

@PerMalmberg can you elaborate on what is the initial timestamp that is missing? Thank you.

Is this

DT(2018_y / 03 / 1, hours{ 12 }, minutes{ 0 }, seconds{ 0 })

Maybe some documentation could be added to the CronScheduleTest.cpp file to indicate how to write an initial timestamp.

@nkinar The first test value needs to be the first calculated schedule, calculated based on the from argument (inclusive). In this case, as we're looking at the smallest unit, it has to be the same as the from point itself.

The test also shows what it calculates and expects: https://github.com/PerMalmberg/libcron/actions/runs/10177199677/job/28148138238?pr=38#step:4:8

[PerMalmberg]

Test passing, LGTM!

Thanks @PerMalmberg that makes more sense now. The from argument needs to be a time before the cron event occurs. The later comparisons are made at the time when the cron event should occur. All checks have now passed, and I've run the tests locally as well on my machine.
