DL
Usage: DL[+] time

This command pauses your SiB™ program for the amount of time specified.
The time parameter is by default a value in milliseconds; however the following suffixes are permitted:
s = seconds, m = minutes, h = hours.  For example, DL 1h will delay execute for one hour. 
Your SiB™ continues to operate during that time and unless notifications are disabled, your SiB™ will accept and queue commands received by IM.
This command can be enhanced with the + symbol, for example: DL+ 1h.  This symbol instructs your SiB™ to use calibrated time.  See
HELP CALIB for more information.

RUNAT
Usage: 

 RUNAT time
 [code]
 ...
Defines a program to run at a specific time of day.
The time is given in HH:MM 24 hour format.
Example:
RUNAT 12:00
IM It is noon

SL
Usage: SL[+] time|off|button

Sleeps for the given amount of time.
If 'off' is supplied rather than a time, the SiB™ will go to sleep with NO MEANS of waking up.
If 'button' is supplied rather than a time, the SiB™ will go to sleep until a button press is detected.
When issuing this command, the SiB™ will go into a deep sleep state.  It will sleep for the specified amount of time.
The time parameter is in milliseconds, however the following suffixes are permitted: s = seconds, m = minutes, h = hours.
If a sleep time longer than one hour is specified, the SiB™ will wake up every hour and check for new notifications until the time runs out.
This allows the sleep cycle to be interrupted; i.e., to run another program, to stop or reconfigure the SiB™, etc.
The SL command can be enhanced using the + symbol, where the time to sleep will be calculated using the result for CALIB TIME.  
The deep sleep can also be interrupted by a button press.
If the button is in SiB™ mode, a button press will wake up the device and initiate the button-click sequence; the resulting program will 
be loaded and the current running program will not resume.

SLB
Usage: SLB [time]

By default (with no time specified), SLB will put the SiB™ to sleep until a button press is detected.
If a time is provided in milliseconds, the SiB™ will go to sleep and wake up after the given time OR when a button press is detected.

UDL
Usage: UDL time_us

This function sleeps for the given number of microseconds.
The time parameter here is accepted only in microseconds.
