Before a token expires we want to refresh it since it is faster to refresh a token, than to request a new one. However, we want to build in some resilience in the system to clock skew, so we want to consider a token expired a few seconds/minutes before it would actually expire.

WebClock Skew. Clocks are buffered through a clock routing network. Clock signals are delayed with respect to the original clock. Paths are defined starting at a source register and terminating at a destination register; Path delay: T P D = T c l k − t o − q + T c o m b. p a t h d e l a y T_{\rm PD}=T_{\rm clk-to-q} + T_{\rm comb.\ path\ delay ...
