Some embodiments of the time resilient system and methods disclosed herein can be configured to detect and defend against invalid time signals. According to various embodiments of the disclosed technology, the time resilient system include a receiver for collecting time signals sourced from an external clock. By way of example only, the external clock may be a high precision clock housed within a Global Positioning System. Other embodiments may include an internal clock calibrated to a time reflected on the external clock so that the internal clock and the external clock are synchronized. Additionally, a controller may monitor changes in time signals of the external over a period of time against the internal clock, where the system is alerted of a timing attack when the time signals collected from the receiver deviate a pre-determined time range with the time of the internal clock.
