      I've been storing epoch time stamps in nvram for some VIP events

      >>> import pycom; pycom.nvs_set('VIP', 1591319102); print(pycom.nvs_get('VIP'))
      1591319102
      

      But a typo has just shown me that this is only going to work till Jan 19 2038

      >>> import pycom; pycom.nvs_set('VIP', 2147483649); print(pycom.nvs_get('VIP'))
      -2147483647
      

      I'm such a sloppy programmer!

        Yes, NVRam only fits 32bit integers (signed). 2,147,483,647 is the maximum value you can fit in!
        Of course you can create your own workaround to use multiple keys.
