AsyncMysqlConnectResult::startTime

The start time for the connection operation, in seconds since epoch

Description

public function startTime(): float

Return Values

  • float - the start time as float seconds since epoch.

Examples

Every connection has a connection result. You get the connection result from a call to AsyncMysqlConnection::connectResult. And one of the methods on an AsyncMysqlConnectResult is startTime(), which tells you when the connection operation started.

Note that

  elapsedMicros() ~== endTime() - startTime()
