Unit test testTimeline fails

Code configuration: ./configure. testTimeline.c --> force the seed to be 1673630953 on line 514.

Result:

[00000.0] main: Seed = 1673630953
Passed test_get_time_bin
[00000.1] testTimeline.c:test_get_integer_time_begin():259: time_begin incorrect: expect=-16 got=0 diff=-16; current=0 displacement=0, dti=16

Seems like an edge case. Maybe something we introduced in 2bfe2f88?
