Ok, you can do the following:

1) Create a new phrase:
Phrasetype: Timezones
Varname: timezone_gmt_plus_0545
Text: (GMT +5:45) Nepal Standard Time

2) Edit ./includes/adminfunctions.php
Find:

PHP Code:

        '5.5' => $vbphrase['timezone_gmt_plus_0530'], 


Add under:

PHP Code:

        '5.75' => $vbphrase['timezone_gmt_plus_0545'], 


3) Edit ./includes/functions_misc.php
Find:

PHP Code:

        '5.5' => 'timezone_gmt_plus_0530', 


Add Under:

PHP Code:

        '5.75' => 'timezone_gmt_plus_0545', 


Not tested, but this should do the trick.
