Precise time management using local time base

A method comprising:

• receiving, by a peripheral interface circuit from a host circuit, an indication of a current value of a global timebase, wherein the global timebase is based on a first clock signal;
• updating, by the peripheral interface circuit using the indication, a first local timebase, wherein the first local timebase is based on a second clock signal;
• comparing, by the peripheral interface circuit, the first local timebase to a second local timebase from a peripheral control circuit, wherein the second local timebase is based on a third clock signal;
• and
• updating, by the peripheral control circuit, the second local timebase based on the comparing.

A system comprising:

• a host circuit, wherein the host circuit is configured to maintain a global timebase based on a first clock signal having a first frequency;
• and
• a peripheral device that includes:
• an interface circuit configured to:
• maintain a first local timebase based on a second clock signal;
• and
• correlate the first local timebase to the global timebase;
• and
• a control circuit configured to:
• maintain a second local timebase based on a third clock signal;
• and
• after a completion of a correlation of the first local timebase to the global timebase, correlate the second local timebase to the first local timebase.
