# Once we have the CkDateTime object, we can get the date/time in many different formats:

# Get as a RFC822 GMT string:
set bLocalTime 0
puts [CkDateTime_getAsRfc822 $dtTime $bLocalTime]

# Get as an RFC822 string in the local timezone.
# (remember, the daylight savings that existed at the given time in the past is applied)
set bLocalTime 1
puts [CkDateTime_getAsRfc822 $dtTime $bLocalTime]

# Get as a 32-bit UNIX time (local or GMT..)
# The Unix time is number of seconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC). 
set unixTime [CkDateTime_GetAsUnixTime $dtTime $bLocalTime]
puts "Unix time: $unixTime"

# One can also get the as a "DtObj" object for accessing the individual
# parts of the date/time, such as month, day, year, hour, minute, etc.
# The DtObj can be obtained in the GMT or local timezone:
set dtObj [new_CkDtObj]
