Long Running Query

Bluehost advises this is a long running query and it’s showing up in my logs quite often:
# Query_time: 2.725949 Lock_time: 0.000072 Rows_sent: 0 Rows_examined: 1
…

SET timestamp=1403539692;
UPDATE <code>tsx_options</code> SET <code>option_value</code> = '1403539689' WHERE <code>option_name</code> = 'dfads_transient_data_deleted_time'

Can anyone please tell me what this is doing?

Thanks!
