Looks like CORE_TIMER register is useful for us here.

Some useful text from T-series datasheet:

• Make sure your code handles when CORE_TIMER wraps.
• If you're assigning wall-clock timestamps, consider what should happen when the clock skips forward or backward due to an NTP update.
• To prevent clock drift, you must continually re-synchronize the system clock to CORE_TIMER. TheT-series clock error at room temperature is 20 ppm. This is 2 ms per 100 seconds, so a re-sync of core-clock to host-clock must be done at least every 50 seconds to maintain 1 ms accuracy. Check your own computer's clock specs for a source of additional clock error.
