Fructosamine & A1c: Both of these are measures of average levels of blood glucose. Fructosamine test measures glycosylation of serum proteins and hb a1c measures glycosylation of hemoglobin.

Timing: Both measure glycosylation (sugar binding) of proteins, but they measure different proteins with different half-lives in the body. Fructosamine measures average glucose over the past 10-14 days; a1c measures average glucose over the past 3 mod. Both are weighted toward the most recent days.
