还是不行。
查到该书：
C:\Program Files\Rational\ClearCase\doc\help\cc_ref\query_language.htm
书中的解释如下，按照该解释写的语句应该是：
cleartool find "Y:\code\test" -type f -version "created_since(02-16-2008.2:0:0)" -print
created_since (date-time)
但是这样执行也不成功，错误提示相同。
附录：该书的说明
In all cases, TRUE if the object was created since date-time. The date-time argument can have any of the following formats:
date.time | date | time |now where:
date
:=
day-of-week | long-date
time
:=
h[h]:m[m][:s[s]] [UTC [ [ + | - ]h[h][:m[m] ] ] ]
day-of-week
:=
today |yesterday |Sunday | ... |Saturday |Sun | ... |Sat
long-date
:=
d[d]–month[–[yy]yy]
month
:=
January |... |December |Jan |... |Dec
Specify the time in 24-hour format, relative to the local time zone. If you omit the time, the default value is 00:00:00. If you omit the date, the default is today. If you omit the century, year, or a specific date, the most recent one is used. Specify UTC if you want to resolve the time to the same moment in time regardless of time zone. Use the plus (+) or minus (-) operator to specify a positive or negative offset to the UTC time. If you specify UTC without hour or minute offsets, Greenwich Mean Time (GMT) is used. (Dates before January 1, 1970 Universal Coordinated Time (UTC) are invalid.)
