Is there an easy method to do an on the fly conversion of a standard epoch time (seconds from 1970) to more readable date format?
Does Unix have anything built in to do this? (4 Replies)
hello gurus,
i want a perl/shell script which once invoked should convert a set of EPOCH timestamps to local time ( IST..i want) .
how does it work ,i have an idea on that..but writing a perl/shell script for it is not possible for me...so i need help for the same.
my exact requirement is... (2 Replies)
how can I get the current standard epoch time (seconds from 1970) in a shell script?
I know I could do this with a bit of perl of even c++ but i want to do it in Bourne shell..... (14 Replies)
I need to convert an epoch time from a file into a standard UTC time and output it in the same format but I'm not sure what's the best approach
here's the input file and the bold part is what I need to convert.

I am trying get time difference of two dates in secs. Initially I want to convert a standard date format to epoch for two dates and then subtract the two epoch dates.
Example :
date -d "2007-09-01 17:30:40" '+%s'
But this gives me below error
date: illegal option -- d

Hi All,
Please read the below data carefully.

Hi there
I'm using this script to convert command line history with Epoch time stamp to human readable. While it works fine with users with /bin/csh shell, it fails to convert for users with /bin/bash shell. Why is this happening? I even changed and added * and after the # but it still didnt... (2 Replies)
Hi. I have timestamps that I am trying to convert to epoch time. An example:
I am trying to convert this to an epoch timestamp but have one little glitch. I have this:

epoch = int(time.mktime(time.strptime(date_time, pattern)))
print epoch... (1 Reply)

DESCRIPTION
TPM Quote Tools is a collection of programs that provide support for TPM based attestation using the TPM quote operation.
A TPM contains a set of Platform Configuration Registers (PCRs). In a well configured machine, some of these registers are set to known
values during the boot up process or at other times. For example, a PCR might contain the hash of a boot loader in memory before it is
run.
The TPM quote operation is used to authoritatively verify the contents of a TPM's Platform Configuration Registers (PCRs). During provi-
sioning, a composite hash of a selected set of PCRs is computed. The TPM quote operation produces a composite hash that can be compared
with the one computed while provisioning.
To use the TPM quote operation, keys must be generated. During provisioning, an Attestation Identity Key (AIK) is generated for each TPM,
and the public part of the key is made available to entities that validate quotes.
The TPM quote operation returns signed data and a signature. The data that is signed contains the PCRs selected for the operation, the
composite hash for the selected PCRs, and a nonce provided as input, and used to prevent replay attacks. At provisioning time, the data
that is signed is stored, not just the composite hash. The signature is discarded.
An entity that wishes to evaluate a machine generates a nonce, and sends it along with the set of PCR used to generate the composite PCR
hash at provisioning time. For this use of the TPM quote operation, the signed data is ignored, and the signature returned is used to val-
idate the state of the TPM's PCRs. Given the signature, the evaluating entity replaces the nonce in the signed data generated at provi-
sioning time, and checks to see if the signature is valid for the data. If so, this check ensures the selected PCRs contain values that
match the ones measured during provisioning.
A typical scenario for an enterprise using these tools follows. The tools expect AIKs to be referenced via one enterprise-wide Universally
Unique Identifier (UUID). The program tpm_mkuuid creates one.
For each machine being checked, an AIK is created using tpm_mkaik. The key blob produced is bound to the UUID on its machine using
tpm_loadkey. The public key associated with the AIK is sent to the entities that verify quotes. Finally, the expected PCR composite hash
is obtained using tpm_getpcrhash. When the expected PCR values change, a new hash can be generated with tpm_updatepcrhash.
The program to obtain a quote, and thus measure the current state of the PCRs is tpm_getquote. The program that verifies the quote
describes the same PCR composite hash as was measured initially is tpm_verifyquote.
