Constructs an Era instance.

Parameters:

name - the era name (e.g., "BeforeCommonEra" for the Julian calendar system)

abbr - the abbreviation of the era name (e.g., "B.C.E." for "BeforeCommonEra")

since - the time (millisecond offset from January 1, 1970 (Gregorian) UTC or local time) when the era starts, inclusive.

localTime - true if since specifies a local time; false if since specifies UTC
