Hello,
DateTimeToString(dt_time, "mmm-dd-yy hh:mm:ss", myDateTime);
Now how to get back TDateTime from dt_time in above format?
StrToDateTime() requires MM/DD/YY HH:MM:SS format
Is there any other direct function?
Thanks,
Sudesh |

StrToDateTime() uses the formats that are assigned to the global
date/time formatting variables, such as ShortDateFormat and
ShortTimeFormat.

I always wondered why StrToDateTime() takes no format parameter.
This is definitely a design flaw from my point of view.

Wow, that works even on my German computer! Can anybody explain
why? I had thought that VarToDateTime() would recognize dt_time
being a String and then call StrToDateTime() internally, but it
seems to have a conversion routine of its own, ridiculously
superior to StrToDateTime() when it comes to convert from String
to TDateTime. Or is it just coincidence, "mmm-dd-yy hh:mm:ss"
being one of few formats known to VarToDateTime()? |

VarToDateTime() takes a Variant as input. When the Variant holds a
String value, the Win32 API VarDateFromStr() function is called. My
guess would be that Microsoft natively supports more parsing options
then the VCL does.

It does.

The Win32 API is used first. Only if it fails, then TryStrToDate() is
called. If that fails, then TryStrToFloat() is called. If that also
fails, then an exception is raised.

Possibly. There is no information on that.
