Hi,

When creating log table, I want to record what time my method being called, up to millisecond.

At first I'm using this :

System.DateTime localDateTime = DateTimeUtil::applyTimeZoneOffset(DateTimeUtil::getSystemDateTime(), DateTimeUtil::getUserPreferredTimeZone());
logTable.ID = localDateTime.ToString('yyyyMMdd_HHmmss.fff');

This is no working, so change to this:

Also only give me 0 for he millisecond.

Some thread give idea to use WinAPI::GetTickcount(), https://community.dynamics.com/forums/thread/details/?threadid=a7ca3807-2760-4b5e-bab8-7dce477659c6, but I think it is not suitable since it is normally for calculate process time between two tickCount.

Thanks

Teevo, the problem likely is that you're converting the System.DataTime value to utcDateTime (by using DateTimeUtil) and because utcDateTime doesn't support milliseconds, the information gets lost there.

Yes,

I ended up using that instead.

Many thanks.

Hi @Teevo,

Try this (it worked for me)

System.DateTimeOffset dt = System.DateTimeOffset::Now; int ms = dt.Millisecond;

Best regards,

Hi Martin,

When testing, I always get zero if using System.DateTime::Now().

I'm wondering whether I'm doing correctly or not ?

Here is my test :

Thanks.

AX/F&O normally doesn't work with miliseconds, therefore I don't expect that getSystemDateTime() gives you this information. System.DateTime::Now should.

Hi @Teevo,

if you want to get milliseconds you can use DateTimeOffset

System.DateTimeOffset dt = System.DateTimeOffset::Now; int ms = dt.Millisecond;

Hi Layan,

Meaning like the first statement ?

System.DateTime localDateTime = DateTimeUtil::applyTimeZoneOffset(DateTimeUtil::getSystemDateTime(), DateTimeUtil::getUserPreferredTimeZone());
logTable.ID = localDateTime.ToString('yyyyMMdd_HHmmss.fff');

it's not working. or I did it wrongly ?
