Invalid marketStartTime

[khughes]

Hi
Am I correct in thinking that the marketCatalogue marketStartTime is always GMT? And includes daylight saving adjustments?

The marketStartTime returned for an event tomorrow is 29/03/2015 at 01:09 but as the daylight saving comes into effect at 1am then the period from 1am to 2am effectively does not exist. So is this an error or am I missunderstanding the way times are returned by API-NG? This is causing me a problem with datetime conversions.

Here is the JSon request and response:

Market start times are UTC times and therefore 01:10 tomorrow is perfectly valid.

The local time of that event will be 02:10 but the UTC time is non-adjusted. That way market start times are always correct wherever you are in the world.

Standard functions exist in most languages to convert date/times to/from UTC.

Hi Betdynamics,

Thanks for your reply.
Yes that makes perfect sense. I have found that the problem is actually the function I am using to convert from a UTC string to a local DateTime. It works fine and caters for daylight saving unless the UTC time happens to fall in the 'non-existent DST time period', as in this case. So it's not an API issue at all, just a small headache for me!

What O/S and language are you using?

If Windows/C#, then retrieve the date as a UTC date and then use the DateTime ToLocalTime() method to convert to the local time.

I'm using Windows/Delphi and I've solved the problem now. It is a known bug in the particular date/time utility library I am using and there is a workaround. So all sorted and thanks for your replies, much appreciated.
