Hi,
i'm working on Windows, with FPC 2.6.4.
This is my code:
Code: [Select]  Memo1.Lines.Clear;
  Memo1.Lines.Add(FormatDateTime('hh:nn:ss.zzz', Now()));
  Memo1.Lines.Add(FormatDateTime('hh.nn.ss:zzz', Now()));
  Memo1.Lines.Add(FormatDateTime('hh@nn@ss.zzz', Now()));

This is the output:
Code: [Select]15.56.01.109
15.56.01.109
15@56@01.109
Seems that FormatDateTime change the ":" with the ".".

The colon in FormatDatetime is replaced by the TimeSeparator from the
FormatSettings, that's by design and very useful when writing
international applications. Therefore, if you need the colon in the
time string set the TimeSeparator to ':', or use a quoted colon in the
format string:

Code: [Select]s := FormatDateTime('hh":"nn":"ss.zzz', Now());
