iat property

int iat
getter/setter pair

The ID token's issued-at time, in seconds since the Unix epoch. That is, the time at which this ID token was issued and should start to be considered valid.

The Firebase SDKs transparently refresh ID tokens every hour, issuing a new ID token with a new issued-at time. If you want to get the time at which the user session corresponding to the ID token initially occurred, see the auth_time property.

Implementation

int iat;
