While writing a Smart Contract you might come across a time-based requirement. In such a situation, you should be able to store time in the Smart Contract.
So, how to store time in a Smart Contract?
In solidity, we use integer to store time in Unix time format.
Take a look at the below Smart Contract.
Points to be noted:
- We are using the type unit (unsigned integer) to store the Unix timestamp.
- In solidity, ‘block.timestamp’ gives the current time. We can verify this by calling the ‘getCurrentTime()’.
- We can also perform different actions such as ‘==’, ‘≤’, ‘≥’ with the Unix time format.
