After spending a few hours debugging time server not working for me, I realized that global-components/templates/rpc-signalling.template.c that was added earlier this year contains the following


/*- set badge = str(configuration[].get("%s_attributes" %'"') -*/


/*- do badges.sort() -*/


int /*? ?*/_largest_badge(void) {

   return /*? badges[len(badges) - 1] ?*/;



Unfortunately for me, my Trusted Build generated camkes had the attributes numbered 1,2,3,10,11,12,13 and therefore the above core was claiming that the time_server_largest_badge is 3 L. Obviously, the issue is the combination of the str and sort, resulting in the last badge being the one largest lexicographically, not numerically L. Replacing the str with int (and correspondingly removing the strip) solved the problem for me.


P.S. Well, solved that particular problem for me, not the problem of time server not working – looks like now I will have to debug
