Thanks for the headstart...I believe I have something that works....
The function I have written below gives:
IDL> x=[1,2,3,5,6,7,9,45,46,47,48,49,50,51,56,59]
IDL> print, time2str(x)
% Compiled module: TIME2STR.
1-3,5-7,9,45-51,56,59

function time2str, x
dx=(x-shift(x,1))[1:*]
l=where(dx ne 1)
times=''
nl=n_elements(l)
nx=n_elements(x)
if l[0] eq -1 then times='0-59' else begin
if l[0] eq 0 then times=strtrim(string(x[0]),2)+','
if l[0] ne 0 then
times=strtrim(string(x[0]),2)+'-'+strtrim(string(x[l[0]]),2) +','
for i=0, nl-2 do begin
if ((l[i+1]-l[i]) gt 1) then begin
times=times+strtrim(x[l[i]+1],2)+'-'+strtrim(x[l[i+1]],2)+', '
endif else begin
times=times+strtrim(x[l[i+1]],2)+','
endelse
endfor
if (nx-1)-l[(nl-1)] eq 1 then times=times+strtrim(string(x[nx-1]),2) else
$
times=times+strtrim(x[(l[nl-1])+1],2)+'-'+strtrim(string(x[n x-1]),2)
endelse
return, times
END
