currentBlockTime
number
Time of the current Block in seconds.
During execution, this is the timestamp of the Block that this Transaction will be included in.
During verification, this is the timestamp of the latest Block + 15 seconds which represents the earliest possible timestamp of the Block that this Transaction will be included in.
currentCallerContract
The Address of the smart contract that directly invoked the contract.
Will be undefined if the smart contract method was not invoked by another smart contract, but instead was invoked by a user directly.
networkNumber
number
The current number of the network.
randomNumber
number
Returns a cryptographically secure random number.
