// e.g., execInterval = 60, but wireshark shows packets every
// ~57.3-57.4s => 60/57.35 =~ 1.0465
// 60÷((58.40+58.36+58.49+58.47+58.46+58.10+58.14+58.11+58.48)÷9) =~ 1.02855
// This can also be approached by measuring time between two
// flashes of the onboard ESP LED: it flashes when wakeup pulse
// is being triggered.
//
// Might be sensitive to temp? At least rtctime module from nodeMCU
// provides a solution to this and states this is due to temperature :(
//
// Experiments running on battery every 60s, forcing NTP re-sync
// every 30 cycles (i.e., 30min, from forceResync above) shows
// good enough accuracy, drifting less than one second between
// each resync ; without, drifting would be ~1min every 10 min.
