ShortTimeFormat
Variable
Short version of the time to string format SysUtils unit
  var ShortTimeFormat : string;
Description
The ShortTimeFormat variable provides the short (compact) formatting used for certain time to string conversions.
 
It is used by the TimeToStr, DateTimeToStr and DateTimeToString routines (the latter when the 'c' or 't' formatting is used). The following formatting character strings can be used in the ShortTimeFormat string:
 
= Hour with no leading 0's
hh  = Hour as 2 digits
= Minute with no leading 0's
nn  = Minute as 2 digits
= Seconds with no leading 0's
ss  = Seconds as 2 digits
= Milli-seconds with no leading 0's
zzz  = Milli-seconds as 3 digits
Notes
The default value is calculated from LOCALE_ITIME and LOCALE_ITLZERO
