Currency rates wrong date import

[skorbofos]

standard mechanism for the import of currencies rates, I needed when changing the dates at 00:00:01 import a new exchange rate for the time zone UTC + 3 but the exchange rate is imported old

jobs for CRON are written to a database table in time UTC table cron_schedule,  despite the server configuration and database UTC + 3

how to fix?
