Instances of time represent a particular time-of-day.
Since they only store hours, minutes and seconds within a day,
they cannot be used to compare times across midnight
(i.e. they should not be used as timeStamps).
Use instances of Timestamp (and read the comment there) to do this.
Time now returns the time in the local timezone.
Use Time utcNow to get the time in the UTC zone.
Note: time was changed recently to keep the number of milliseconds since midnight.
However, all existing instance creators so far only create time instances with 0-millis.
I.e. Time now still returns a time with second precision.
It is not done currently, to remain backward compatible, as users may get confused
to see t1 > t2 although they print the same (as long as the printed representation does not
include the milli seconds).
On the other side: a change of the default printformat is not done now,
as it may affect many existing applications.
Any application which needs the millisecond precision time should call the new
Time nowWithMilliseconds.
Examples:
|t|
t := Time now.
Transcript showCR:t.
|t1 t2|
t1 := Time now.
(Delay forSeconds:10) wait.
t2 := Time now.
t2 - t1

"return a new Time, reading a printed representation from aStream using a formatString.
The formatString is similar to the one used when printing.
On error, exceptionalValue is returned.
If exceptionalValue is a one-arg block, an error message is passed as argument.
Format:
%h hours, 00..23 (i.e. european) 0-padded to length 2
%u hours, 00..12 (i.e. us) 0-padded to length 2
%m minutes, 00..59 0-padded to length 2
%s seconds, 00..59 0-padded to length 2
%i milliseconds, 000..999 0-padded to length 3
%f fractional seconds any length, but only milliseconds are read
%a am/pm
an optional length after the % gives a field length;
i.e. %2h%2m%2s parses '123557' as 12:35:37
Please consider using a standard format, such as iso8601.
