Date and time formats<br />
<strong>User</strong> is allowed to specify date and time formats which will be used in SMS messages<br />
when timestamp processing commands are used. <strong>Module</strong>’s configuration contains four<br />
format strings:<br />
Date format is used by date processing commands (prefixes LD, UD)<br />
Time format is used by time processing commands (prefixes LT, UT)<br />
General format 1 and 2 are used by timestamp processing commands (prefixes T1<br />
and T2, respectively)<br />
Format strings can contain specific character combinations, related to date/time<br />
information, which will then be replaced with corresponding values during parsing.<br />
Apart from this, format strings can contain additional characters – they will be copied to<br />
resulting timestamp string unchanged.<br />
Available specifiers are:<br />
Specifier<br />
Replaced with<br />
YYYY year, four digits (e.g. 2010)<br />
YY year, two digits (e.g. 10)<br />
MM month, two digits (01..12)<br />
DD day in month, two digits (01..31)<br />
HH hour, two digits (00..23)<br />
MN minute, two digits (00..59)<br />
SS second, two digits (00..59)<br />
For example, if user defines “General format 1” as:<br />
DD/MM/YYYY, HH:MN:SS<br />
and when it will be applied to RTC registers by a SMS command:<br />
#T1.IR0<br />
