Implementations§

source§

impl<'api> TimestampCallApi<'api>

source

pub fn set(&self, now: u64) -> Result<WrappedCall>

Set the current time.

This call should be invoked exactly once per block. It will panic at the finalization phase, if this call hasn’t been invoked by that time.

The timestamp should be greater than the previous one by the amount specified by MinimumPeriod.

The dispatch origin for this call must be Inherent.

Complexity
  • O(1) (Note that implementations of OnTimestampSet must also be O(1))
  • 1 storage read and 1 storage mutation (codec O(1)). (because of DidUpdate::take in on_finalize)
  • 1 event handler on_timestamp_set. Must be O(1).
