Early in Star Trek Beyond, the Enterprise lands at Yorktown Station, for shore leave. On the Station, two Vulcans tell Spock that Spock Prime has died. Spock looks at a sheet that has a picture of Spock Prime and lettering underneath that I thought were birth and death dates, but the scene was so fleeting that I am not sure of this.
Was the lettering birth and death dates? Or something else? And, if birth and death dates, what was the death date? If the death date was the date in the alternate time line when Spock Prime died, he would seem much younger -- by decades -- than his actual life span. If the death date reflected his actual life span it would be in the future of the alternate time line. How is this ambiguity resolved?
