[sr-dev] [kamailio/kamailio] acc: save cdr entries in UTC (#1358)

[Carlos Cruz Luengo]

### Description

ACC module allows setting datetime fields in UTC via [time_mode param](http://kamailio.org/docs/modules/devel/modules/acc.html#acc.p.time_mode).

However, this setting does not cause cdr entries to be saved in that format and I haven't found any equivalent parameter to achieve this.

### Troubleshooting

Analyzing the code for MySQL database storage I have found that [_db_time2str_ex_ function defined in _db_ut.c_](https://github.com/kamailio/kamailio/blob/master/src/lib/srdb1/db_ut.c#L256) uses localtime(). 

### Possible Solutions

Changing localtime() to gmtime() cdrs are saved in UTC, but it would be desirable to add a new module param that makes this configurable.

### Additional Information

  * **Kamailio Version** - output of `kamailio -v`

```

* **Operating System**:

<!--
Details about the operating system, the type: Linux (e.g.,: Debian 8.4, Ubuntu 16.04, CentOS 7.1, ...), MacOS, xBSD, Solaris, ...;
Kernel details (output of `uname -a`)
-->

```
Linux 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u3 (2017-08-06) x86_64 GNU/Linux
```

Should I proceed and try to get a working PR to add this new modparam or there is currently a way to get this that I have missed (apart from setting system time to UTC)?

Thank you and regards,
