Arithmetics

In LIGO, timestamps can be added to integers, allowing you to set time constraints on your smart contracts. Consider the following scenarios.

Incrementing

const today: timestamp = Mavryk.get_now();

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;

Decrementing

const today: timestamp = Mavryk.get_now();

const one_day: int = 86400;

const in_24_hrs: timestamp = today - one_day;

Subtracting

Timestamps can be subtracted, that means, we can use minus (-) between two timestamps:

const today: timestamp = Mavryk.get_now();

const some_date: timestamp = "2035-01-01t10:10:10Z" as timestamp;

const secs_until_some_date: int = some_date - today;

Notice that the result of such subtraction is an int, which describes the difference in seconds between the two timestamps.
