1. A computer-implemented method, comprising:
executing, in a virtualized environment, a time-sensitive task;
periodically requesting a current time value from a reference clock source;
determining that the current time value differs from an expected time value; and
causing an application executing the time-sensitive task to operate in an overdrive mode for period of time, wherein the overdrive mode uses additional resources or capacity to recover a difference in time between the current time value and the expected time value.
