Constant sgx_tstd::time::UNIX_EPOCH

pub const UNIX_EPOCH: SystemTime = SystemTime(time::UNIX_EPOCH)

An anchor in time which can be used to create new SystemTime instances or learn about where in time a SystemTime lies.

This constant is defined to be "1970-01-01 00:00:00 UTC" on all systems with respect to the system clock. Using duration_since on an existing SystemTime instance can tell how far away from this point in time a measurement lies, and using UNIX_EPOCH + duration can be used to create a SystemTime instance to represent another fixed point in time.
