Milliseconds with wxDateTime/wxLogFormatter?

[Tobias Abt]

Hi *,

 

I’m trying to add milliseconds to my log-output:

 

wxString MyLogFormatter::FormatTime (time_t time) const

{

     return wxDateTime(time).Format("%Y.%m.%d-%H:%M:%S.%l");

}

 

But all I get for milliseconds is “000”…

 

What should I do get milliseconds?

 

 

Regards and thanks for your help,

Tobi

"time_t" is just unsigned int i.e. "count of seconds", there are no
miliseconds. You need few other calls to get mili's.

Take a look here: http://docs.wxwidgets.org/trunk/classwx_date_time.html

e.g. constructor:

wxDateTime (wxDateTime_t hour, wxDateTime_t minute=0, wxDateTime_t
second=0, wxDateTime_t millisec=0)

or Set() methods...

Greetings,

perhaps you should give a try to this one:

http://docs.wxwidgets.org/trunk/classwx_date_time.html#a0db1c9bac7b2d27d589cad2a38d1438c

( "UNow()" static function )

see example for "Now()" to see how to use it:
http://docs.wxwidgets.org/trunk/classwx_date_time.html#a6e6c37a0414bb4831e2cc03b37f498a2

Hi,
Thanks for your reply.
On my machine time_t looked bigger ;)

So from what I gathered it is not possible to add (the correct) milliseconds to the timestamp:
The time is set in the constructor of wxLogRecordInfo and if 'time_t' does not provide the necessary accuracy, it makes little sense to add a different time later.
Well, it would do for the main-thread, but as soon as another thread starts logging, the time is completely wrong (about 1s on my machine).

Or am I missing something?

Tobi

wxLog functions only use time_t, but you also have a possibility to
associate arbitrary values in the log records, so you could use this to
store a higher precision timestamp in addition to time_t. It won't be as
seamless as just using time_t but should definitely work.
