here's an example of the test passing then failing with 2 different dates.


-------------------------
vagrant@kohadevbox:~$ sudo date -s 'Sun Jan 29 01:41:55 UTC 2017'
Sun Jan 29 01:41:55 GMT 2017
kohadev-koha@kohadevbox:/home/vagrant/kohaclone$ prove t/db_dependent/Members/IssueSlip.t
t/db_dependent/Members/IssueSlip.t .. ok
All tests successful.
Files=1, Tests=3,  3 wallclock secs ( 0.03 usr  0.00 sys +  2.10 cusr  0.12 csys =  2.25 CPU)
