If `time` is already a transition point on `date`, replace the existing code with `code`. The addition of a transition, but not the replacement of the code of an existing transition, invalidates all iterators. The behavior is undefined unless `24 > time.hour()`, `date` is within the valid range of this timetable, and `0 <= code || k_UNSET_TRANSITION_CODE == code`. == Synopsis Declared in `<bdlt_timetable.h>` [source,cpp,subs="verbatim,replacements,macros,-callouts"] ---- void addTransition( xref:BloombergLP/bdlt/Date.adoc[Date] const& date, xref:BloombergLP/bdlt/Time.adoc[Time] const& time, int code); ---- [.small]#Created with https://www.mrdocs.com[MrDocs]#
