It seems to me that a lot of people much smarter than I have have wrestled with this problem for more than 50 years, and still don't have an instantaneous solution. Other solutions: * Don't suspend the machine. Problem solved. * If you must suspend the machine, bring it up some reasonable length of time before you require accuracy from your clock. Problem solved. * Invest in a decent GPS receiver, and install chrony and gpsd on the machine. Doing so may get the system clock in synch faster; it may not. Doing that sort of thing is well documented on the gpsd home page. -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
