Working with bash and date

Hello all,

I'm trying to substract 1 minute from the current date and take the hour and minute (for filename purpose).

1) If I want hour an minute from current time I can use:
Code:
timetmp=$(date +"%H:%M")

2) To substract 1 minute from current time I can use:
Code:
timetmp=$(date --date "$dte -1 minute")

Well now, how can I extract the minute and hour from example 2 like on example 1?

Could some1 please help me with this (i hope) simple trouble?
Thanks

HYLAFAX-SHUTDOWN(5)						File Formats Manual					       HYLAFAX-SHUTDOWN(5)

NAME
etc/shutdown - server shutdown control file DESCRIPTION
If the file etc/shutdown is present it describes when a HylaFAX server is to be shutdown and may contain a descriptive message to return to clients explaining the reason for the shutdown. This file is used by the hfaxd(8) program. The file has the following format: <year> <month> <day> <hour> <minute> <deny> <disconnect> <shutdown message text> The first line defines the date and time the server should be shutdown and the time preceding at which unprivileged clients should be denied service or disconnected; these fields are described in more detail below. Any lines that follow the first are taken as the text of a message to return to clients when notifying them of a scheduled shutdown or when denying them service. <year> The decimal year; e.g. 1996. <month> The decimal month; e.g. 10 for October. <day> The decimal day of the month in the range [1..31]. <hour> The decimal hour since midnight; in the range [0..23]. <minute> The decimal minute after the hour; in the range [0..59]. <deny> The time prior to the shutdown time at which to deny service to unprivileged clients. This value is specified as decimal number in the form HHMM; e.g. 130 for 1 hour and 30 minutes. <disconnect> Time time prior to the shutdown time at which to disconnect unprivileged clients that are logged in to the server. This value is specified as a decimal number in the form HHMM. NOTES
This file is typically created using the ``SHUT'' command supported by hfaxd(8). SEE ALSO
