Chapter 18 : Timestamps


You cannot get the current time in LIGO but you can get the starting time of the current block :

const today: timestamp =;


In LIGO, timestamps can be added to integers :

const today: timestamp =;
const one_day: int = 86_400;
const in_24_hrs: timestamp = today + one_day;
const some_date: timestamp = ("2000-01-01T10:10:10Z" as timestamp);
const one_day_later: timestamp = some_date + one_day;
const _24_hrs_ago: timestamp = today - one_day;


You can compare timestamps using the same comparison operators applying to numbers.

const not_tommorow: bool = ( == in_24_hrs);
