sandbox next_billing_time don't give billing

[shen_ming]

Hi.

I got subscription detail like this

{'billing_info': {'cycle_executions': [{'cycles_completed': 1,
'cycles_remaining': 0,
'sequence': 1,
'tenure_type': 'TRIAL',
'total_cycles': 1},
{'current_pricing_scheme_version': 1,
'cycles_completed': 0,
'cycles_remaining': 0,
'sequence': 2,
'tenure_type': 'REGULAR',
'total_cycles': 0}],
'failed_payments_count': 0,
'next_billing_time': '2020-04-27T10:00:00Z',
'outstanding_balance': {'currency_code': 'USD',
'value': '0.0'}},

'next_billing_time': '2020-04-27T10:00:00Z' But now it is "'2020-04-27 13:05:13.918096'"

The billing it not coming.

And the transactions of this subscription  list don't change counts.

I want to know whether the sandbox have time delay for billing created?

At the end.

It happened at 

'last_payment': {'amount': {'currency_code': 'USD',
'value': '10.0'},
'time': '2020-04-27T22:51:31Z'},

Which later about 12 hours ?

it seems your first 'sequence' is of type 'TRIAL', therefore there are no billing before this sequence ends.

I wonder why next-billing-time is not when TRIAL expires. that'd be logical and easier to handle the expiration date of the trial
