Araldite Rapid ALWAYS hardens off a bit "rubbery" in my experience. "Original" araldite (the 24 hour stuff) is much harder when fully cured.
But for this, gel type superglue will do fine, PROVIDED you make sure to get the glue ONLY where you need it (use a pin, or toothpick to apply it). I'm assuming here that like most clocks, in yours both the hour hand and minute hand are driven by a what looks like a single shaft but is actually 2 shafts, the outer being a tube with inner shaft running inside it. You do NOT want glue in the wrong place (down the tube, which capillary action can easily do if you're not very careful - and especially if using "runny" superglue rather than gel type).
Loctite do a range of "glues" specially designed for metal,(called "anerboeric" - sp? - or some word like that) including a glue ideal for this. I forget which number but a quick Google onto Loctite's web site will soon put you right. Also ARC Eurotrade (see sticky in Metalworking Section) sell a complete range of a competing product (just as good) and have a complete explanation of all available types on their web site.
+1 for JB weld but it's a bit "sticky" to get cleanly into a small area like this.

AES
P.S. DO remember to clean the area thoroughly before applying the glue. Tiny strip of fine wet n dry first, followed by acetone (nail varnish remover) will be good, but again, be carful not to allow if to run down the "drive tube" - capillary action again).
