We have been testing a SIM applet on both the MC7455 and the MC7430 and have encountered an issue
with the response to the proactive command “PROVIDE LOCAL INFORMATION” (request date/time).
The date & time returned by this command is incorrect.
First to ensure that the modem supports this command, the applet issues the TERMINAL PROFILE command.
The device responds with (coding defined in TS 102 223 Section 5.2) byte 8, 07 ~ 0000 0111,
indicating that PROVIDE LOCAL INFORMATION for date-time command is supported.
However when the PROVIDE LOCAL INFORMATION command is issued by the applet:
- 801200000B12D0098103012603820281829000 -> applet request for date/time (26 local info 03 date time)
This device responds with:
- 8014000015148103012603020282810301002607081060000040FF910B which translates into a date in year 2080.
- Time Stamp Decode: 081060000040FF = 2080/01/06-00:00:04/z=FF
Is this a known issue?
Additional input that might be useful to understand this problem:
